5-4x=12-2x isolate your x's on one side 5=12-2x+4x 5-12=-2x+4x simplify -7=2x divide by 2 x=-7/2, or x=-3.5
-2x=-4x*24 x=12
As written, that's 2(x - 6) You may have meant 4x^2 - 2x - 12 which would be 2(2x + 3)(x - 2)
-2x + 6 <= 4x + 18 -2x <= 4x + 12 -12 <= 6x -2 <= x
4x + 2 + 2x - 2x = 14 4x = 14 - 2 4x = 12 x = 3
