3x-2y=6 -2y=-3x+6 y=1.5x-3
3x+2y=6 2y=-3x+6 y=-1.5x+3
-3x + 2y = 12-3x + 3x + 2y = 3x + 122y = 3x + 122y/2 = 3x/2 + 12/2y = (3/2)x + 6
2y = 3x-6 y = 1.5x-3 in slope intercept form
Multiply first equation by 1.5, giving 3x + 3y = 12, but we are told that 3x + 3y = 6. If there isn't an error in the question then 2 = 1!
