Answer 1 · 2015-09-01T22:04:01

I found the value 13.

74=5y+9
74-9 =5y
5y=74-9
5y = 65
y= 65/5

y=13#

$y = 13$ $y = 13$

Your goal here is to isolate $y$ $y$ on one side of the equation. The first thing you need to do is subtract $9$ $9$ 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 $13$ .
