Solving Two-Step Equations with Parentheses

Samuel bought 3 tires for $79.95 each and some rims for $59 each. He spent a total of $534.85. Which equation could be used to find the number of rims, r, Samuel bought?

• 3(79.95) - 59r = 534.85

• 79.95r - 59(3) = 534.85

• 3(79.95) + 59r = 534.85

• 79.95r + 59(3) = 534.85
