color(purple)"y = 1"

Explanation:

color(tan)("Subtract 13 on both sides:")

5y+cancel13= 18
color(white)(aaa)-cancel13 color(white)() -13

13 cancels out on the left side, and when you subtract 13 from 18 on the right you get 5:

5y = 5

color(red)("Divide both sides by 5 to get y by itself.")

(cancel"5"y)/cancel"5"=(5)/5

Now you are just left with y on the left side and 1 on the right side.

Therefore,
color(magenta)"y = 1"
