Problem 28
Using the addition property of equality first, solve each of the following equations. $$\frac{1}{2} a+2=-7$$
Problem 29
Simplify the following expressions by combining similar terms. In some cases the order of the terms must be rearranged first by using the commutative property. $$12 y+3+5 y$$
Problem 34
Apply the distributive property to each expression and then simplify. $$2(5 x+1)+10$$
Problem 35
