    1/5 (10x-15) = 1/4 (12x-8)

    1/5 (10x-15) = 1/4 (12x-8)

    Simplify:

    (1/5) (10x) + (15) (-15) = (1/4) (12x) + (1/4) (-8) (Distribute)

    2x+-3=3x+-2

    2x-3=3x-2

    Subtract 3x from both sides.

    2x-3-3x=3x-2-3x

    -x-3=-2

    Add 3 to both sides.

    -x-3+3=-2+3

    -x=1

    Divide both sides by - 1.

    -x/-1 = 1/-1

    x=-1
