\(2\text{h} + 9 = 21\)

\(12 - \cfrac{3}{5}\text{p} = -27\)

\(11 = 2\text{b} + 17\)

\(-17 = 6\text{p} - 5\)

\(2\text{g} - 3 = -19\)

\(13 = \cfrac{\text{g}}{3} + 4\)

\(13 - 3\text{d} = -8\)

\(-\cfrac{2}{3}\text{m} - 4 = 10\)

\(-5\text{y} - 25 = 25\)

Some friends decide to go to the aquarium together. Each person pays $7.50 to get in. They spend a total of $40 for the shark exhibit. The total cost is $70. Solve \(7.5\text{x} + 40 = 70\) to find how many people went to the aquarium.

Identify Structure Brent had $26 when he went to the fair. After playing 7 games, he had $15.50 left. Solve \(15.50 = 26 - 7\text{p}\) to find the price for each game. Then list the Properties of Equality you used to solve the equation.
