What is the equation you're trying to solve?
anonymous
  • 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
  • anonymous
after you got something like this: ax=b do this: x=b/a andyou are done
anonymous
  • anonymous
so now how would you solve 4x=18?

that is the problem i am working on now

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.

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

-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
  • anonymous
wait.. how did you do that? :/
anonymous
  • anonymous
i think you are missing something
ghazi
  • 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
