Answer:
x = - 4/3
Step-by-step explanation:
Distribute:
3x - 12 = 12x.
-12 = 9x
x= - 12/9 or - 4/3
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
