Answer:

#y = 13#

Explanation:

Your goal here is to isolate #y# on one side of the equation. The first thing you need to do is subtract #9# from boh sides of the equation

#74 - 9 = 5y + color(red)(cancel(color(black)(9))) - color(green)(cancel(color(black)(9)))#

#65 = 5y#

Now divide both sides of the equation to get #y# alone on the right-hand side

#65/5 = (color(red)(cancel(color(black)(5)))y)/color(red)(cancel(color(black)(5)))#

#13 = y#

And there you have it, #y# is equal to #13#.
