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?

that was not the right problem. the problem is 3X+y=7 for y

Yes. I said that it was an EXAMPLE. It is very similar to the actual problem...

Ok. Maybe this will help... Solve for y in the following problem. 5x + y = 2 This is the example problem.  5x + 5x + y = 2  5x Subtract 5x from both sides. 0 + y = 2  5x Do you see how 5x  5x = 0? I just combined like terms. y = 2  5x 0 + anything is what was being added to 0.

So do the same thing in the original problem. 3x + y = 7 This is the problem. 3x  3x + y = 7  3x Subtract 3x from both sides. 0 + y = 7  3x Combine like terms. y = ???? Can you do what's above??
