9x-2x-16=5x-11\left(2-x\right)
Use the distributive property to multiply -2 by x+8.
7x-16=5x-11\left(2-x\right)
Combine 9x and -2x to get 7x.
7x-16=5x-22+11x
Use the distributive property to multiply -11 by 2-x.
7x-16=16x-22
Combine 5x and 11x to get 16x.
7x-16-16x=-22
Subtract 16x from both sides.
-9x-16=-22
Combine 7x and -16x to get -9x.
-9x=-22+16
Add 16 to both sides.
-9x=-6
Add -22 and 16 to get -6.
x=\frac{-6}{-9}
Divide both sides by -9.
x=\frac{2}{3}
Reduce the fraction \frac{-6}{-9} to lowest terms by extracting and canceling out -3.
