Question

when solving an equation, how do you determine what number to add,subtract,multiply or divide by on both sides of that equation?

Answer 1

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

Answer 2

Hmm example..

Answer 3

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

Answer 4

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.

Answer 5

Sounds about right

Answer 6

"isolate the variable" is the important part
