What's the answer to 3 (x-4) = 12x

3 (x-4) = 12x

multiply the bracket by 3

(3) (x) = 3x

(3) 9-4) = -12

3x-12=12x

move 3x to the other side

sign changes from + 3x to - 3x

3x-3x-12=12x-3x

-12=9x

divide both sides by 9 to get x by itself

-12/9=9x/9

-12/9=x

reduce - 12/9 by dividing by 3

-12/3=-4

9/3=3

answer:

-4/3 or - 1 1/3

x = - 4/3

Step-by-step explanation:

Distribute:

3x - 12 = 12x.

-12 = 9x

x = - 12/9 or - 4/3
