-3x + 2x = 6Let's abbreviate left part by cancellation:-x = 6The answer will be:x = -6
If 3x + 3 = 2x + 6 then 3x - 2x = 6 - 3 x = 3
-3x+14 = -4 -3x = -4-14 -3x = -18 x = 6
3x - 6 = -3x + 36Add 3x to each side:6x - 6 = 36Add 6 to each side:6x = 42Divide each side by 6:x = 7
y = 3x 3x + 4y = 30 3x + 4(3x) = 30 3x + 12x = 30 15x = 30 x = 2 y = 3x y = 3(2) y = 6 (2, 6)
