\left(21\times 3+1\right)x=-18
Multiply both sides of the equation by 3.
\left(63+1\right)x=-18
Multiply 21 and 3 to get 63.
64x=-18
Add 63 and 1 to get 64.
x=\frac{-18}{64}
Divide both sides by 64.
x=-\frac{9}{32}
Reduce the fraction \frac{-18}{64} to lowest terms by extracting and canceling out 2.
