-12x+18\left(x-3\right)+3\left(x-1\right)=2\left(x+1\right)-\left(x+3\right)
Multiply both sides of the equation by 6, the least common multiple of 2,3,6.
-12x+18x-54+3\left(x-1\right)=2\left(x+1\right)-\left(x+3\right)
Use the distributive property to multiply 18 by x-3.
6x-54+3\left(x-1\right)=2\left(x+1\right)-\left(x+3\right)
Combine -12x and 18x to get 6x.
6x-54+3x-3=2\left(x+1\right)-\left(x+3\right)
Use the distributive property to multiply 3 by x-1.
9x-54-3=2\left(x+1\right)-\left(x+3\right)
Combine 6x and 3x to get 9x.
9x-57=2\left(x+1\right)-\left(x+3\right)
Subtract 3 from -54 to get -57.
9x-57=2x+2-\left(x+3\right)
Use the distributive property to multiply 2 by x+1.
9x-57=2x+2-x-3
To find the opposite of x+3, find the opposite of each term.
9x-57=x+2-3
Combine 2x and -x to get x.
9x-57=x-1
Subtract 3 from 2 to get -1.
9x-57-x=-1
Subtract x from both sides.
8x-57=-1
Combine 9x and -x to get 8x.
8x=-1+57
Add 57 to both sides.
8x=56
Add -1 and 57 to get 56.
x=\frac{56}{8}
Divide both sides by 8.
x=7
Divide 56 by 8 to get 7.
