18y+26+10y+18

To simplify the expression given:

18y + 26 + 10y + 18

First, combine like terms. Like terms are terms that have the same variables raised to the same powers. In this case, the like terms are 18y and 10y.

Combine 18y and 10y: 18y + 10y = 28y

Now, combine the constant terms, which are 26 and 18: 26 + 18 = 44

So, the simplified expression would be:

28y + 44
