3x+6+2\left(x-4\right)=x-3\left(x+3\right)
Use the distributive property to multiply 3 by x+2.
3x+6+2x-8=x-3\left(x+3\right)
Use the distributive property to multiply 2 by x-4.
5x+6-8=x-3\left(x+3\right)
Combine 3x and 2x to get 5x.
5x-2=x-3\left(x+3\right)
Subtract 8 from 6 to get -2.
5x-2=x-3x-9
Use the distributive property to multiply -3 by x+3.
5x-2=-2x-9
Combine x and -3x to get -2x.
5x-2+2x=-9
Add 2x to both sides.
7x-2=-9
Combine 5x and 2x to get 7x.
7x=-9+2
Add 2 to both sides.
7x=-7
Add -9 and 2 to get -7.
x=\frac{-7}{7}
Divide both sides by 7.
x=-1
Divide -7 by 7 to get -1.
