See a solution process below:

First, subtract $color(red)(13)$ from each side of the equation to isolate the $y$ term while keeping the equation balanced:

$13 - color(red)(13) - 5y = 8 - color(red)(13)$

$0 - 5y = -5$

$-5y = -5$

Now, divide each side of the equation by $color(red)(-5)$ to solve for $y$ while keeping the equation balanced:

$(-5y)/color(red)(-5) = (-5)/color(red)(-5)$

$(color(red)(cancel(color(black)(-5)))y)/cancel(color(red)(-5)) = 1$

$y = 1$

How do you solve 13-5y = 813-5y = 8?
