SOLUTION: Ok So my question is very simple
X-Y=3
X+Y=7
After I put it in slope intercept form I get
-Y=-X+7
Y=-X+3
Ho do I get rid of that negative Y?

Ho do I get rid of that negative Y? Answer by Theo(13342) (Show Source):
You can put this solution on YOUR website! x - y = 3
subtract x from both sides of the equation to get:
-y = -x + 3
multiply both sides of the equation by -1 to get:
y = x - 3
that's one way.
here's another way.
x - y = 3
add y to both sides of the equation to get:
x = y + 3
subtract 3 from both sides of the equation to get:
x - 3 = y
by the laws of commutation, if a = b then b = a which allows you to make the equation be equal to:
y = x - 3
