I have 2 solve the equation and check my answer.
And find what x is!
Thanks if u answer it!

What have you done so far.
Remember you do the same action on BOTH sides..

7x=3x-80
7((times) how do u write times besides x)-3x+80=0
(7-3)x+80=0
4x+80=0
now the q is hoe do I continue it?

So you are here


Just take 80 from both sides and then you'll see what to do next..

hu I don't get that so u add 4x+80??

You want to move the 80 to the left in the form
so you get



What's next ?

So then u divide 80 divided by 4 and u get -20??
If it correct thanks sooooo much :)

Do you see how that worked ?
Same action on both sides..

Yes thxn so much!
Can u also help me w/ another problom?

Lets see what we can do then..

kk the next one is
5(2x-3)=6x=9
I have so far is..
5(2x-3)=6x=9
10x-15-6x-9=0
10x-24-6=0
10x-6x-24=0
4x-24=0
4x=24
x=6
is that correct??
if it is thanks soooooo much u rock I have a math final tom and u helped me a lot! :) <3

5(2x-3)=6x=9 this is incorrect as there's two = signs.
what should the second one be ?

I don't know but how would u figure it out?

Well reread your work book ;)

If it's + then your working is dead right..
Does it make sense for you now ?

What to try another..

Yes it is a + srry about that but thanks so much you ill ask you another one soon k thanks so much I apreaciate it :) <3

so here's another one...
2(4c-7)=8c+14
8c-14-8c+14
8c-8c-14+14
= 0
so the answer is 0?
is it right?

No need to post it here.
Keep the problems in the same place ;)
Makes it easier for my old brain to work on...

Kk lol
Wait what do u mean "Keep the problems in the same place "?
