Working together, Joy and Steve collected 53 pounds of aluminum cans for recycling. If Joy collected 20 pounds, find the number of pounds, x, that Steve collected. Using x as your variable write an equation to solve.

• 20x=53

• x-20=53

• x-53=20

• x+20=53

Robin made $24.00 one weekend and some money, m, the next. She made a total of $65.00. How much money did Robin make the second weekend? Using m as your variable write an equation to solve this problem.
