2x-3\left(x-2x-2\right)=x-12-\left(x-3\right)
Use the distributive property to multiply -2 by x+1.
2x-3\left(-x-2\right)=x-12-\left(x-3\right)
Combine x and -2x to get -x.
2x+3x+6=x-12-\left(x-3\right)
Use the distributive property to multiply -3 by -x-2.
5x+6=x-12-\left(x-3\right)
Combine 2x and 3x to get 5x.
5x+6=x-12-x-\left(-3\right)
To find the opposite of x-3, find the opposite of each term.
5x+6=x-12-x+3
The opposite of -3 is 3.
5x+6=-12+3
Combine x and -x to get 0.
5x+6=-9
Add -12 and 3 to get -9.
5x=-9-6
Subtract 6 from both sides.
5x=-15
Subtract 6 from -9 to get -15.
x=\frac{-15}{5}
Divide both sides by 5.
x=-3
Divide -15 by 5 to get -3.
