38-7x+21=9\left(x+1\right)
Use the distributive property to multiply -7 by x-3.
59-7x=9\left(x+1\right)
Add 38 and 21 to get 59.
59-7x=9x+9
Use the distributive property to multiply 9 by x+1.
59-7x-9x=9
Subtract 9x from both sides.
59-16x=9
Combine -7x and -9x to get -16x.
-16x=9-59
Subtract 59 from both sides.
-16x=-50
Subtract 59 from 9 to get -50.
x=\frac{-50}{-16}
Divide both sides by -16.
x=\frac{25}{8}
Reduce the fraction \frac{-50}{-16} to lowest terms by extracting and canceling out -2.
