-3x-\left(8+x\right)=12x-6\left(9-2x\right)-38
Multiply both sides of the equation by 12, the least common multiple of 4,12,2,6.
-3x-8-x=12x-6\left(9-2x\right)-38
To find the opposite of 8+x, find the opposite of each term.
-4x-8=12x-6\left(9-2x\right)-38
Combine -3x and -x to get -4x.
-4x-8=12x-54+12x-38
Use the distributive property to multiply -6 by 9-2x.
-4x-8=24x-54-38
Combine 12x and 12x to get 24x.
-4x-8=24x-92
Subtract 38 from -54 to get -92.
-4x-8-24x=-92
Subtract 24x from both sides.
-28x-8=-92
Combine -4x and -24x to get -28x.
-28x=-92+8
Add 8 to both sides.
-28x=-84
Add -92 and 8 to get -84.
x=\frac{-84}{-28}
Divide both sides by -28.
x=3
Divide -84 by -28 to get 3.
