Basically, you're trying to isolate the y... 3x is being added to y. What do you do to make a positive 3x to make it equal zero? Perform this on both sides of the equation.

I can't really give you a full answer, but I can show you an example that is very similar... Solve for y. 5x + y = 2 - 5x + 5x + y = 2 - 5x 0 + y = 2 - 5x y = 2 - 5x Do you get it?
