4x+36+3\left(x-2\right)=16x
Use the distributive property to multiply 4 by x+9.
4x+36+3x-6=16x
Use the distributive property to multiply 3 by x-2.
7x+36-6=16x
Combine 4x and 3x to get 7x.
7x+30=16x
Subtract 6 from 36 to get 30.
7x+30-16x=0
Subtract 16x from both sides.
-9x+30=0
Combine 7x and -16x to get -9x.
-9x=-30
Subtract 30 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-30}{-9}
Divide both sides by -9.
x=\frac{10}{3}
Reduce the fraction \frac{-30}{-9} to lowest terms by extracting and canceling out -3.
