What is the equation you're trying to solve?

- anonymous

myko is right, but when you move a number to the other side of the eual sign you need to change the sign of the number itself. 4 becomes -4 and -4 becomes 4

- anonymous

well i understand that part but i cant go on further, i always get stuck :(

- anonymous

after you got something like this:
ax=b
do this:
x=b/a
andyou are done

- anonymous

so now how would you solve 4x=18?

I dont know if this is right or wrong but i dont know where to go from there :/

- anonymous

that is the problem i am working on now

- anonymous

If you're getting the "X's" on one side then make sure you include the x. You're combining like terms. So it would be +3x under the -3x and the -7x. But you got it right so far after you get there your going to combine the +2 and the -22.

- anonymous

okay i can go on from there, thanks for your help :)

- anonymous

No problem.

- ghazi

ghazi :D

- anonymous

hi :D

- ghazi

:D BP hey ;)

- anonymous

can you help me please :(

- ghazi

BP i am :D

- ghazi

-3x + 2 = -7x-22
now bring like terms at one side so terms with variable lets say the ones with "x" bring them together and numbers together ;) so
-3x+7x=-22-2
4x=-24
now divide both sides by 4 and you will have
x=-6
\[\frac{ 4x }{ 4 }=\frac{ -24 }{ 4 }\] so x= -6 ;)

|dw:1362525310743:dw| clear?

- anonymous

wait.. how did you do that? :/

- anonymous

i think you are missing something

- ghazi

nope i did , just bring 4x in the left so sign will be changed and take +2 on the right so sign will be changed and it will be +4x and on the right it will be -2 because sign gets interchanged
