3x-4y=15
-4y=15-3x
y=(15-3x)/-4
if you know how much is X, then you will know the value for Y.

3x - 4y = 15
3x = 15 + 4y
3x - 15 = 4y
(3x - 15) / 4 = y

Possible, genius.
4y = -3x + 15

3x - 4y = 15
3x - 15 = 4y
3 (x-5)/4 = y

3x - 15 = 4y
3 ( x - 5 ) divided by 4 = y

Impossible to solve, since X and Y could be interchangeable! You need 2 equations both with X and Y variables to solve for either.
cheers
