You'd multiply 12 and 3, which is 36, then make up 2 numbers that equal 36. My suggestion is to divide it by 2, to get 18+18. Hope this helps!
You said y + y/3 = 12
Multiply each side
by 3 : 3y + y = 36
Combine like terms
on the left side: 4y = 36
Divide each side
by 4 : y = 9
Multiply each side
by 3 : 3y + y = 36
Combine like terms
on the left side: 4y = 36
Divide each side
by 4 : y = 9
