    Part A) This equation has only one solution.

    Part B:

    4 (2x-5) = 4

    Simplify both sides of the equation.

    4 (2x-5) = 4

    Simplify:

    4 (2x-5) = 4

    (4) (2x) + (4) (-5) = 4 (Distribute)

    8x+-20=4

    8x-20=4

    Add 20 to both sides.

    8x-20+20=4+20

    8x=24

    Divide both sides by 8.

    8x / 8 = 24 / 8

    x=3
