Answer:

x = 179/9 or 19 1/9

Step-by-step explanation:

Distribute:

-12x-(12x+4)+12=12x-6(3x+56)

then add your numbers:

-12x-12x- 4+12=12x-6(3x+56)

-12x- 12x+ 8 =12x-6 (3x+56)

then combine like terms:

-12x-(12x+4)+12=12x-6(3x+56)

-24x + 8 = 12x - 6 (3x + 56)

distribute again:

-24x + 8 = 12x- 6 (3x + 56)

-24x + 8 = 12x- 18x -336

combine like terms once again:

-24x + 8 = 12x -18x -336

-24x + 8 = -6x -336

subtract 8 from both sides of equation:

-24x + 8 = -6x -336

-24x + 8- 8 = -6x -336- 8

simplify:

-24x = -6x -344

add 6x to both sides:

-24x = +6x -344 + 6x

simplify: -18x = -344

divide: -18/-18 = -344/-18

Simplify and your answer should be 172/9 or 19 1/9
