-2(x-4)=2 Solve for x
x=10? I'm not sure
oh I got this let me get my note pad
Oh ok Thanks.
hmm I got 3 X=3 wanna see my math
|dw:1378261211585:dw| YEs I would like to see your math
(That drawing does no justice to my writing)
x=-3 you dropped the Negative sign and you only divide by 2 not -2 soo -6/2 = -3 help with more?
oh sorry I dropped the negative haha oops lol you need anymore help?
Yes please I mean I'mma try and work them out then post them n here then let you see if you get the same answer
both of us post our work
haha sure :)
so what's the problem
ugh I hate fractions
ME TOO! I know we have to distribute.
let me go get my stupid Journal again
wait you can't divide fractions huh?
not really I think -2/3(4x+5)= -10/3 Not sure though
show me the math
well, - 10/3
I udes a calculator for that :p
haha well i got the same so i'd have to say yeah for that one
|dw:1378262425168:dw| Ho to we find X now?
ugh is there any without fractions that we can do 1st
Well, When i'm dong them I have to give Proofs so I kinda want to do them in order
hey umm I got to go back to the 2nd prob we did it wrong if it is −23(4x+5)=−103 then we can get rid of the annoying fractions (which everyone hates) by multiplying both sides by −3 and starting with 2(4x+5)=10
I got to go
10= - 2/3(4x+5) solve for x so confused
ok soo distribute -2/3 to (4x+5) would = - 10/3 right? I have a hard time with fractions
Dude im so confused...
All you do is distribute the -2/3 out to 4x and 5. Meaning multiply each.
so - 8/3x + -10/3x ???
what do I do now?
Oh, no that x is only with 4x |dw:1378265256944:dw| So it's just that Now what you do is move numbers to the left, and leave x's by themselves. btw, when you have a + - you can just change it into a -.
I have to get rid of the fractions..... How?
Well if we wanted to turn 1/3 into 1, what would we multiply by?
Yea, 3 :) so multiply everything by 3
so even the 10 on the left?
Yup! What you do to one side you do it to the other.
so now I have 30=24x-30x?
No no no, you multiplied it by 3 to cancel the fraction: |dw:1378265696130:dw|
because 8/3 is the same as (1/3)*8
ooohoooooohhh soo 30=-8x-10x so now add 8 to both sides?
Remember, the x was just with 4, not bother 4 and 5 So it's just 30=-8x-10
oh ok |dw:1378265973030:dw|
You can't add/subtract variables with numbers.
|dw:1378266129825:dw| This should make it easier
so 40=-8x then divide by 40 so x= -1/5 OR -20?
You divide the number with the variable: |dw:1378266378331:dw|
Ohh ok im use to the variable being on the left
So what was your final answer?
can you help with more? I gots more fractions :'(
Get rid of the fraction
multipy by 3?
so 1/3x multiplied by 3 = 1 right? so it would bee -24=1+x?
|dw:1378266795708:dw| Don't forget that lonely x over there, and when you multiply a variable by anythingg, it stays.
Now combine like terms
oh yeah 3x+x and x is = to 1 soo yeah 4x -24=4x divide by 4 x=-6
3x+2(x+5)=15 how do I distribute this?
first do 2*x then 2*5
2*x is 2x then 10 soo 10x?
no, keep them separate
so 2x and 10
Yup, remember that + sign in between them
You know what to do from here right?
then simplify... which would be 5x+10=15
Yea, you're getting it :) now, subtract 10 from bother sides
soo5x=5 after I subtract 10 from both sides
now finish it off!
divide by 5 soo x=0
because or does it equal 1...
Piece of cake though right? :)
yeahh so x- (3x-9)=-5 I need to distribute so x*3x and x*9 soo 3x-9x=-5
No, not the x: |dw:1378268239626:dw|
^Just an example btw
so wait how would I do this distributing step this 1 is confusing me for some reason
soo its x-3x+9=-5?
mhm, keep going
and what do you get?
-2x=-14 so divide by 2 x=-2
divide by -2, and x=7
grr im stupid sometimes
No, you just need practice Anyways, it's kind of late here and I have my own things to finish, so good luck I'm sure ou'll be fine on the rest :)
glad you got help @EvonHowell
Can you help with more? I mean I sorta got it down so it won't be too much work hopefully
-2x=-4x+24 i forgt what i was suppose to do dang it!!
oh sorry I didn't notice you replied till right now (darn Facebook) umm what do you need help with?
-2x=-4x+24 I can't remember what to do
I love these
lol they are NOT fractions I like them too
haha yeah I STRONGLY DISLIKE FRACTIONS!
it's be a decimal that's not fun
got to divide by 11 now... but that = -15/11 so hw do we figure it out now?
haha I already did it it's -0.7333333333333
well, I'm putting x=-15/11 down
haha good choice
haha fun lol
|dw:1378271557746:dw| im pretty sure I messed up somwhere here you may want to check
:O how come you get pretty writing!?!
I am a ambassador I know these things :p
Yes, I am a ambassador for the Site OpenStudy they people who own the site tell me what to do and I do it I work for them really. but....... 8x-4=19+5x
aww huge mistake showing me that letter thing haha neater but harder to control
4 to go and they all have fractions!! Damn it!!!
oops sorry dang it my bad OS forgive me
Blah haha no worries i really don't mind
yeahh your tellin me!!
haha ok time to start this unforgivable prob.
yep i think we have to distribute first
ugh joy (total sarcasm)
what was the problem again anyways XD
|dw:1378273183449:dw| I called in back up for this spawn of a demon
who? did you call?
I love that man I swear!
haha I didn't know it was a guy
its a guy!
I love that man he need to hurry up though
sorry how was I supposed to know
well HE is helping me
okay so whats your question here? A long post I am confused.
what you just help sailorgirl with
haha you just saw it
When I searched for the problem above I saw someone being hanged in picture lol
haha I know i am sooo sorry lol it's just I really hate fractions XD
got 3 more too.... DX
nvm Happy to help :)
ok so I know i need to distribute! but how this confuses me really bad
@EvonHowell post it separately ..this one is lagging for me
okk sooo now we got 3 more to doo 1/2 (2x-6)=2x
haha back to the original page
have to get my laptop charger brb
12(2x−6)=2x 2x−62=2x 2x−2·32=2x
@EvonHowell you still there?
Yep lost my pencil but found it :D
XD haha yay for pencils lol
So did you get why X=-3
where did you get the 12?
OMG @EvonHowell you're a freshmen I barely realized (Wow I feel dorky haha)
NOO That was last years Picture im a Sophomore
it was 1/2 sorry I didn't write the slashy things oh haha I was gonna say how cute
@EvonHowell haha sorry for calling you a freshmen lol haha
lol we only got 2 more YAYAYAY and its ok :) i get called a freshmen everyday at school then I buck up and tell them i'm not then they run away 2/3(3x+18)=5x-9
XD haha why do you run everyone was once a freshmen in their life haha believe it or not I was once a freshmen lol (that's such a dorky thing to say) x=7
I dont run they run when I buck up to them! and I need the steps btw :p
haha oh lol I always get mistaked for a senior i'm a junior XD mkay let me list them
2/3(3x+18)=5x−9 2(3x+18)3=5x−9 2(3x+18)=3(5x−9)
huh? that confused me ...
its like midnight where im at everything is confusing me now
haha same here it's 11:27pm
ooh nice nevada where?
cali thats cool
yeah I love living here
yeah im in fn nevada a hour away from vegas hey well, I am going to go to bed im tired ive been doing my math for 6 hours now still have english to do soo ttyl
