    x=2/5, x=-6

    Step-by-step explanation:

    |4 - 2x| = |3x + 2| =

    4-2x=3x+2

    -2x-3x=2-4

    -5x=-2

    x=-2/-5=2/5 possibility 1

    -2x+4 = - (3x+2) possibility 2

    -2x+4=-3x-2 (Simplify both sides of the equation)

    -2x+4+3x=-3x-2+3x

    x+4=-2

    x+4-4=-2-4 (Subtract 4 from both sides)

    x=-6
