Hey, Silver, let me see if I can help you out. I'm going to assume that your task is not only to get y on its own side of equality sign, but to solve for y as well.
-3x+2y=2
Okay so our first task, here, is to get the x value away from the y and across the equality sign. To do this, we add 3x to both sides of the equation (remember that, on the y side, we're trying to bring x to zero).
-3x+3x+2y=2+3x 0x+2y=2+3x
2y=2+3x
We still need to rid of the lefthand 2, in order to achieve a lonely y, and so we divide both sides of the equation by that value: 2.
2y/2=2/2+3x/2
The 2's on the lefthand side cancel out to leave y, and we simplify the righthand fractions.
y=1+3x/2
x-4y=8
Same thing here, but because x is positive, we are going to subtract it. Recall that a lone variable is considered to have a numerical value of 1.
