18+7y=2+63y
Multiply both sides of the equation by 9.
18+7y-63y=2
Subtract 63y from both sides.
18-56y=2
Combine 7y and -63y to get -56y.
-56y=2-18
Subtract 18 from both sides.
-56y=-16
Subtract 18 from 2 to get -16.
y=\frac{-16}{-56}
Divide both sides by -56.
y=\frac{2}{7}
Reduce the fraction \frac{-16}{-56} to lowest terms by extracting and canceling out -8.
