6x-\left(x+2\right)+6=3\left(2x-1\right)-2x+3\times 3\left(x-1\right)
Multiply both sides of the equation by 6, the least common multiple of 6,2,3.
6x-x-2+6=3\left(2x-1\right)-2x+3\times 3\left(x-1\right)
To find the opposite of x+2, find the opposite of each term.
5x-2+6=3\left(2x-1\right)-2x+3\times 3\left(x-1\right)
Combine 6x and -x to get 5x.
5x+4=3\left(2x-1\right)-2x+3\times 3\left(x-1\right)
Add -2 and 6 to get 4.
5x+4=6x-3-2x+3\times 3\left(x-1\right)
Use the distributive property to multiply 3 by 2x-1.
5x+4=4x-3+3\times 3\left(x-1\right)
Combine 6x and -2x to get 4x.
5x+4=4x-3+9\left(x-1\right)
Multiply 3 and 3 to get 9.
5x+4=4x-3+9x-9
Use the distributive property to multiply 9 by x-1.
5x+4=13x-3-9
Combine 4x and 9x to get 13x.
5x+4=13x-12
Subtract 9 from -3 to get -12.
5x+4-13x=-12
Subtract 13x from both sides.
-8x+4=-12
Combine 5x and -13x to get -8x.
-8x=-12-4
Subtract 4 from both sides.
-8x=-16
Subtract 4 from -12 to get -16.
x=\frac{-16}{-8}
Divide both sides by -8.
x=2
Divide -16 by -8 to get 2.
