5x - 4 = 3x + 6 5x - 3x = 6 + 4 2x = 10 x = 5
-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
