    -3 (9x-7)

    Step-by-step explanation:

    first multiply

    20x2=40

    and now its - 40x+13x+21

    then add same variables

    -40x+13x=-27x

    now its - 27x+21

    then rewrite the equation

    3 x 7=21

    -3 x 9x = 27x

    now its (-3 x 9x) + (3 x 7)

    then the multiply thingy and you got the answer
