3x - y = 12 is the same as 3x - 12 = y, or y = 3x - 12.

6x - 12 = 3x + 12 Add twelve to both sides.6x - 12 + 12 = 3x + 12 + 12Simplify.6x = 3x + 24Subtract 3x from both sides.6x - 3x = 3x + 24 - 3xSimplify.3x = 24Divide both sides by 3.x = 8The answer is x = 8.

12 + 3x = 412 - 12 + 3x = 4 - 123x = -83x/3 = -8/3x = -8/3x = -(2 2/3)
-3x + 2y = 12-3x + 3x + 2y = 3x + 122y = 3x + 122y/2 = 3x/2 + 12/2y = (3/2)x + 6
