It you mean when your trying to solve for x or y. The point is to isolate the variable.

Hmm example..

dtan5457 · Answer

3x+6=3
ISOLATE variable. Subtract the 6.

3x=3-6

3x=-3

3 is front of the x, and it's multiplication. Therefore you divide by 3.

x=-1

That's all the question asks. I just don't know how to word it. Best I can get is.......You have to get the variable alone so  you do the opposite  of the equation. ex: If it's x+3=6 ,you do the opposite of +3 which is -3.
