yeah of course

- anonymous

anyway hers the fir question also thanks for helping me by the way

- anonymous

An equation is shown below:
3(2x – 7) = 3
Part A: How many solutions does this equation have? (4 points)
Part B: What are the solutions to this equation? Show your work. (6 points)

- anonymous

you can solve it I will just guide you. :)

- anonymous

im not sure how to do the problem do you think you can help me get on the right path because i have no ideo what to do

- anonymous

3(2x – 7) = 3
Let's solve your equation step-by-step.
6x-21=3
6x-21+21=3+21
6x=24
solve for x

- anonymous

That will be the only solution

- anonymous

ok so can you tell me what you just did so i can learn from it please aslo since you were here to help i faned you and gave you a medal

- anonymous

thanks but you din't have to I will give you ur medal back

- anonymous

u are new

- anonymous

oh ok so i geuse just gove it to you wehn were done

- anonymous

don't givee me a medal I don't need it you are new

- anonymous

i dont realy no how these things work i literly just made account like 7 min ago

- anonymous

LOL

- anonymous

LOL yeah

- anonymous

do you have another question?

- anonymous

uh yeah befor i go on to my next question you said solve x so what do i do add subtract multiply?

- anonymous

24/6=x

- anonymous

i realy suck in math its like my worst subject

- anonymous

oh math is my set subject history is my worst

- anonymous

so divide right

- anonymous

best I mean

- anonymous

yes divide

- anonymous

realy historys my best lol

- anonymous

LOL

- anonymous

next question?

- anonymous

ok one sec

- anonymous

sure

- anonymous

An equation is shown below:
9(3x – 16) + 15 = 6x – 24
Part A: Write the steps you will use to solve the equation, and explain each step. (6 points)
Part B: What value of x makes the equation true? (4 points)

- anonymous

lol

- anonymous

while your solving that ill solve x

- anonymous

cool

- anonymous

bythe way is it 6 divided by 24 or 24 divied by 6

- anonymous

for x

- anonymous

24/6

- anonymous

thanks

- anonymous

yeah

- anonymous

ok i wont interfer anymore sorry

- anonymous

Step by step solution :
Step 1 :Simplify 27x-129 - 6x-24
Pulling out like terms :
1.1 Pull out like factors : 21x - 105 = 21 • (x - 5)
Equation at the end of step 2 : 21 • (x - 5) = 0
Step 3 :Solve 21•(x-5) = 0
Solve : x-5 = 0
Add five to both sides and x-5 cancels so the solution is:
0+5=x

- anonymous

i dont know what to do

- anonymous

so 5+0= 5
so x=5

- anonymous

soory to solve for u

- anonymous

sorry I mean

- anonymous

no i dont even know what you did im lost

- anonymous

im realy realy realy bad at math

- anonymous

oh
with step number one I multiplied 9*3x and got 27x and I multiplied 9 and 16 and got 129

- anonymous

I then pulled down the subtraction sign and got:
27x-129

- anonymous

ok i think im starting to understand

- anonymous

continue

- anonymous

pleasesssss

- anonymous

then you add -24 to both sides:
27+-129+-6x+-24

- anonymous

uh huh

- anonymous

combine like terms:
(27x+-6x)+(-129+-24)

- anonymous

ok

- anonymous

also thank you and sorry for being so complicated

- anonymous

you get 21x

- anonymous

ok and then is that it

- anonymous

21X*-5=0

- anonymous

oh ok

- anonymous

0+5=x

- anonymous

x=5

- anonymous

do you kinda understand?

- anonymous

ohhhhh yeah i get it now

- anonymous

cool

- anonymous

it took me awile lol

- anonymous

its okay at least you got it :)

- anonymous

at first i was like what and then i was like ohhh now i get it

- anonymous

LOL

- anonymous

so was that for part 1 of question 2

- anonymous

yes the explanation was
x=5 is part 2

- anonymous

oh ok so now the finle qestion yay i though i going to bomb this but because of you i have hope thank so much "cying on the inside"

- anonymous

LOL your welcome happy to help :)

- anonymous

"crying tears of joy"

- anonymous

i dont know how to repay you man im just so happy but dont worry these are many tears "i told myself i wasnt going to cry but its just so beautiful"

- anonymous

LOL

- anonymous

da du da FINAL QUESTION "waring incoming major bossss" :boss Battle activated:

- anonymous

An equation is shown below:
5x + 3(x – 5) = 6x + 2x – 15
Part A: Solve the equation and write the number of solutions. Show all the steps. (6 points)
Part B: Name one property you used to solve this equation. (4 points)

- anonymous

here it is the finale question

- anonymous

yayayayayayayayaya im almost done and then i can go to sleeep

- anonymous

LOL

- anonymous

Reorder the terms:
-15 + 5x + 3x = 6x + 2x + -15
Combine like terms: 5x + 3x = 8x
-15 + 8x = 6x + 2x + -15
Reorder the terms:
-15 + 8x = -15 + 6x + 2x
Combine like terms: 6x + 2x = 8x
-15 + 8x = -15 + 8x
Add '15' to each side of the equation.
-15 + 15 + 8x = -15 + 15 + 8x
Combine like terms: -15 + 15 = 0
0 + 8x = -15 + 15 + 8x
8x = -15 + 15 + 8x
Combine like terms: -15 + 15 = 0
8x = 0 + 8x
8x = 8x
Add '-8x' to each side of the equation.
8x + -8x = 8x + -8x
Combine like terms: 8x + -8x = 0
0 = 8x + -8x
Combine like terms: 8x + -8x = 0
0 = 0

- anonymous

remember im not as smart as you so nice slow OH MY GOOOOOOD IT SO COMPLEX

- anonymous

Simplifying
5x + 3(x + -5) = 6x + 2x + -15
Reorder the terms:
5x + 3(-5 + x) = 6x + 2x + -15
5x + (-5 * 3 + x * 3) = 6x + 2x + -15
5x + (-15 + 3x) = 6x + 2x + -15
DO THIS BEFORE OTHER STEPS THAT I JUST POSTED

- anonymous

my brain just stop working for a second there

- anonymous

lol

- anonymous

ok let me try

- anonymous

DO THIS BEFORE OTHER STEPS THAT I JUST POSTED
Simplifying
5x + 3(x + -5) = 6x + 2x + -15
Reorder the terms:
5x + 3(-5 + x) = 6x + 2x + -15
5x + (-5 * 3 + x * 3) = 6x + 2x + -15
5x + (-15 + 3x) = 6x + 2x + -15

- anonymous

ok done

- anonymous

ok

- anonymous

ok

- anonymous

Are the steps kinda helping

- anonymous

man your realy good at math

- anonymous

thanks

- anonymous

oh yes these steps are helping alot there still hard but i can finaly kinda understand and its not like going up to my teachers board and hes like solve this 30 secs and im like "what?"

- anonymous

LOL

- anonymous

with disdain exspration and a tilt to my head

- anonymous

:)

- anonymous

:) but serasly man i realy owe you one every time i see you ill also say rember this favor because now i wont have to reapt this dang thing aging for the 19th time

- anonymous

LOL

- anonymous

what grade are u in in math

- anonymous

"thank the lord my math conquer as arrived" "halleju ha"

- anonymous

LOL

- anonymous

8th going into 9th but even though i suck at math my reading level is alreay at a college levl and i already have online novels

- anonymous

they arnt popular but i can at least say i have them

- anonymous

oh I am in 7th grade but doing 9th grade math at school

- anonymous

back to the du daaaa final question

- anonymous

k

- anonymous

oh realy cool dud i bet we wood be the best of reeainds mat i hate math you like math i can already see the chemstry

- anonymous

freinds

- anonymous

I am a girl but I don't know maybe?

- anonymous

hehe ist ako i have many freinds that are girls in fact you could say that most of my freinds are girls just because the are good at subjests that im bad we get along and they help me thats why i have not been held back thank good for my luck with school

- anonymous

LOL

- anonymous

Thts good you haven't been held back :)

- anonymous

lol anyway reaady to help me deafeat this final boss femal comrade i arms charge

- anonymous

Yep Lets do it!:)

- anonymous

yes it is good i havent been held back nooowww CHARG!

- anonymous

ok so were you able to kinda understand my explanation

- anonymous

yes it is good i havent been held back nooowww CHARG!

- anonymous

ok so were you able to kinda understand my explanation

- anonymous

or do I need to simplify

- anonymous

sorry my computer crashed im back

- anonymous

OK

- anonymous

and i waas so pumped too

- anonymous

lol

- anonymous

but im back

- anonymous

also yeah i understood so keep feeding me little bit like you did before

- anonymous

OK

- anonymous

Reorder the terms:
5x + 3(-5 + x) = 6x + 2x + -15
5x + (-5 * 3 + x * 3) = 6x + 2x + -15 you multiply x and 3 and 5 and 3
5x + (-15 + 3x) = 6x + 2x + -15

- anonymous

ok

- anonymous

Reorder the terms:
-15 + 5x + 3x = 6x + 2x + -15
Combine like terms: 5x + 3x = 8x
-15 + 8x = 6x + 2x + -15

- anonymous

Reorder the terms:
-15 + 8x = -15 + 6x + 2x
Combine like terms AGAIN: 6x + 2x = 8x
-15 + 8x = -15 + 8x

- anonymous

how do i combine the trms

- anonymous

you chose the number that have the same terms, or variable is this case and add subtract multiply or divide them together
In this case we add

- anonymous

show me please

- anonymous

15 + 8x = -15 + 6x + 2x
6x+2x=8x|dw:1439427006386:dw|

- anonymous

sorry for the bad drawing

- anonymous

pfft its ok pffttf its not cute or funny at all pfffttttt

- anonymous

Lol

- anonymous

its ok your awsome so its fine

- anonymous

Add '15' to each side of the equation.
-15 + 15 + 8x = -15 + 15 + 8x
Combine like terms ONCE MORE: -15 + 15 = 0
0 + 8x = -15 + 15 + 8x
In this case the like terms are number, they do not have a variable
so you add -15+15 and get 0

- anonymous

ok

- anonymous

|dw:1439427212957:dw|

- anonymous

So Combine Like terms again BUT ON RIGHT SIDE OF EUAL SIGN: 0 + 8x = -15 + 15 + 8x
-15+15=0
NOW YOU GET:
0+8X=0+8X

- anonymous

ok

- anonymous

you add 0 to the 8x and get
8x=8x
Add '-8x' to THE RIGHT of the equation.
8x + -8x = 8x + -8x
YOU GET: 0
-8X+8X=0
DO THE SAME THING TO THE LEFT SIDE OF EQUAL SIGN:
0=0

- anonymous

|dw:1439427451426:dw|

- anonymous

how do you feel about the problem

- anonymous

ok and now the final final the identity what is it i have no clue

- anonymous

0 is the identity

- anonymous

i feel that you you just made something super cdompicaded in my mind seem simple somehow which is weird because usally when i lose hope i freak out like i just did and then cry but you helped me so im ok

- anonymous

Good glad to help :)

- anonymous

ask me anytime you need help with math

- anonymous

:)

- anonymous

yay im done i could hug you im so happy

- anonymous

LOL i'm glad
