This depend on what you are solving for. But lets do this:
Divide the WHOLE equation by 9. By doing this, you simplify the equation and get y by itself. Now you have -2x+y=8. Isolate y. Do this by adding 2x to each side of the equals sign. you now have y=2x + 8.

Then you will need to isolate the x with the following steps:
