#color(purple)"y = 1"#

#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"#
