okay I am ready and reporting to you help..

x/7 =-10+8

x/7 = -2
x=7 times -2
x=-14

we are solving for x right?

yes

check your answer:
x=-14
x/7 -8
= (-14)/7 -8
=-2-8
=-10

no no you can't do that when x/7 no

why?

whenever you see / it means divide

so therefore we x divided by 7

yeah, i know, when you change sides, it becomes mutiplying

correct

???

so it should be 7x=-14

then divide by 7?

no it's divided here so that can not happen

anytime you have something divided by something you times it

in order for the x or whatever you are solving for.

ok, let's do this one for clarity.......1-n/5=12

subtract -1 from both sides...

you have n/5=11

so the answer is 55?

negative sign!

you should have
-n/5 =11

-11?

oh, I see!!!

guys if you are doing this right than have X=??

-55

1- n/5 =12
1 -1 -n/5 =12-1
-n/5 =11
-n=55
n=-55

yipee!

gr8!
just make sure you don't get confused with the signs

oh I see what you are doing now, I go step by step that is why I was thrown off by what you did

sry!

6t +3=-7

subtract 3 from both sides

and you can always check your answers by substituting x=? in you equation

6t=-10

divide by 6?

yes

answer is -2?

what is -10 divided by 6?

something isn't right, that is not one of my answwer choices

10 goes into 2 five and 2 goes into 6 3 so the answer is -5/3

well your steps are all correct...

I didn't have the lowest denominator

usually the answers are in simplest form, so simplify your fractions

what choices do you have?

I have -5/3 as an answer

no before you said -2

right, but godorovg came up with -5/3 and I have that as an answer choice

I did not simplify

unless it says to do it I would leave as is

15=-15-8u

add 15 to both sides

30-8u

30=-8u

then what?

divide by -8?

yes

15/-4?

-15/4?

yes

I need help with this one
0=1/6y+8=

subtract 8 from both sides

yes

0-8 is 0?

-8?

yes, -8

-8=1/6y

now what?

can I help here, this problem you are making it harder than it has be

because the variable is in the denominator, therefore we have to switch it to the other side

-8=1/6y
-8(6y)=1/6y times 6y

so you multiply both sides with 6y

show me

ok

-8=1/6y?

okay now you tell me

multiply both sides by 1/6?

you multiply both sides with 6y

yes

but it is 1/6 not just six

so y=1/6x8?

yes

or 48?

it should be y=1/-48

oh yes, because it was a -8

since:
1/6y =-8
1/(6 times-8) =y
so, y=1/-48

yes it that is the y=1/-48

okay, thanks guys! I'm tired...going to bed, goodnight! Thanks for your help!

hey no problem glad I could you help you :)

gd nite!

tiffany great job!!

u too!

it's funny that when erinhass says good night , it's actually good morning for me. :)

you just made a fan.

u too.:), and thx.

I don't just do the work for them..

*see

yeah, of course, pls do, i'm all ears :)

okay first what type of math do you help with this mostly?

algebra, calculas, and the basics, just high school stuff.

ok, thx a lot!

that is always my goal as well.

also to get the student to ask questions as well

yeah, interaction helps.

A must in math, because you and the student have to be involved in order to teach

unless they just not getting it.

absolutly right, are you like, a teacher?

No. I am a Physics Engineering major in college

cool, always have love physics, physics rocks!

yeah, and bio sucks

same here!

Chem and Physics oh yeah,,

uh huh

Bio not on your life

Anything to do with math I love

sry, mom needs me to have lunch, gotta go.

okay have nice day

cya latter

talk later :)
