Write an equivalent expression in simplest form for each given expression. Then, choose the answer that explains why the expressions are equivalent.
(A) 2y + 4(y + 1) = y +

First use the Property to simplify the expression in parentheses, then
combine like terms.

(B) 9y + 6 + 2(5 + y) = y +

After applying the Distributive Property, use the Properties to
combine like terms.
