    So I have to subtract 3x from the right side of the equation right?

    so after I move 3x (which is now -3x) to the side of the equation with 12 on it, do I divide by 3x on that side?

    *Do I divide -3x and 12 by 3?

    so first you isolate the y to one side of the equation. But for this problem you would move the x variable to the right side to make the equation easier.

    No, do not divide by 3x. You've subtracted it from the left side to the right. You are done with the 3x. Now you want to isolate 'y'. But you have '2y'..so what should you do?

    so then 2y = 4, So I divide 2 and 4 both by 2? y = 2 ?
