The expression is .

                        (Commutative Property: a + b = b + a)

                    (Associative Property: (a + b) + c = a + (b + c))

                      (Distributive property: a (b + c) = ab + ac)

                                       (Add: )

                                     (Distributive property: a (b + c) = ab + ac)

                                              (Substitution property: 3 + 2 = 5)

The simplified expression is 5q.
