q+40=8q-408
Multiply both sides of the equation by 8.
q+40-8q=-408
Subtract 8q from both sides.
-7q+40=-408
Combine q and -8q to get -7q.
-7q=-408-40
Subtract 40 from both sides.
-7q=-448
Subtract 40 from -408 to get -448.
q=\frac{-448}{-7}
Divide both sides by -7.
q=64
Divide -448 by -7 to get 64.
