I calculated it mentally. This is a good exercise for the brain.

( 1 / 3 ) y + 8 = y 3 + 8 = 16 (1/3)y+8=\frac{y}{3}+8=16

y 3 + 8 − 8 = y 3 = 16 − 8 = 8 \frac{y}{3}+8-8=\frac{y}{3}=16-8=8

3 ( y 3 ) = 3 y 3 = y 1 = y = 8 ( 3 ) = 24 3(\frac{y}{3})=\frac{3y}{3}=\frac{y}{1}=y=8(3)=24

Therefore, y = 24 \boxed{y=24} !
