I added 13y to both sides and got 20=5y-25.  Adding 25 to both sides gives 45=5y so y=9.

Oopse, I mistyped out the steps, here's the corrected version:

1. Isolate the variable terms (those with y) and the constant terms. In other words, get the variable terms on the left side of the equal sign, and get the numbers on the right side.

Add 8y to both sides

-5y + 20 = -25

Subtract 20 from both sides

-5y = -45

2. To solve for y, divide both sides by -13

y = 9

Hope this helps!
