9\left(-x\right)+18+3\left(x-2\right)=0
Use the distributive property to multiply 9 by -x+2.
9\left(-x\right)+18+3x-6=0
Use the distributive property to multiply 3 by x-2.
9\left(-x\right)+12+3x=0
Subtract 6 from 18 to get 12.
9\left(-x\right)+3x=-12
Subtract 12 from both sides. Anything subtracted from zero gives its negation.
-9x+3x=-12
Multiply 9 and -1 to get -9.
-6x=-12
Combine -9x and 3x to get -6x.
x=\frac{-12}{-6}
Divide both sides by -6.
x=2
Divide -12 by -6 to get 2.
