Which procedure justifies whether - 3x (5-4) + 3 (x-6) is equivalent to - 12x-6?

The expressions are not equivalent because - 3 (2) (5-4) + 3 (2-6) = -18 and - 12 (2) - 6=-30

The expressions are not equivalent because - 3 (2) (5-4) + 3 (2-6) = -18 and - 12 (3) - 6 = -42.

The expressions are equivalent because - 3 (2) (5-4) + 3 (2-6) = -18 and - 12 (-2) - 6 = 18

The expressions are equivalent because - 3 (2) (5-4) + 3 (2-6) = -18 and - 12 (1) - 6=-18

    x=1

    Step-by-step explanation:

    -3x (5-4) + 3 (x-6)

    -15x+12x+3x-18

    -3x+3x-18

    -18=-12x-6

    -12x=-18+6

    -12x=-12

    12x=12

    x=12/12

    x=1
