    Answer: x = 5, 3

    Step-by-step explanation:

    1) Remove the parentheses

    x2-7x+12=x-3

    2) Move all terms too one side

    x 2 - 7x+12-x+3=0

    3) Simplify x2-7x+12-x+3 to x2-8x+15

    x2-8x+15=0

    4) Factor x2-8x+15

    (x-5) (x-3) = 0

    5) Solve (x-5) (x-3)

    x = 5, 3
