-16+20y-64=48
Calculate 4 to the power of 2 and get 16.
-80+20y=48
Subtract 64 from -16 to get -80.
20y=48+80
Add 80 to both sides.
20y=128
Add 48 and 80 to get 128.
y=\frac{128}{20}
Divide both sides by 20.
y=\frac{32}{5}
Reduce the fraction \frac{128}{20} to lowest terms by extracting and canceling out 4.
