22y+7-8y=0
Subtract 8y from both sides.
14y+7=0
Combine 22y and -8y to get 14y.
14y=-7
Subtract 7 from both sides. Anything subtracted from zero gives its negation.
y=\frac{-7}{14}
Divide both sides by 14.
y=-\frac{1}{2}
Reduce the fraction \frac{-7}{14} to lowest terms by extracting and canceling out 7.
