See the entire solution process below:

Explanation:

Multiply each side of the equation by #color(red)(3)# to solve for #y# while keeping the equation balanced:

#color(red)(3) xx y/3 = color(red)(3) xx 8/9#

#cancel(color(red)(3)) xx y/color(red)(cancel(color(black)(3))) = (color(red)(3) xx 8)/(3 xx 3)#

#y = (cancel(color(red)(3)) xx 8)/(color(red)(cancel(color(black)(3))) xx 3)#

#y = 8/3# or #y = 2.bar6#
