Ranger's friend, Foster, wanted to challenge him by creating this expression involving two sets of parentheses with fractions:1 3 (9x − 15) + 4(x + 1 2 ) Ranger showed his first two steps below. 1. Distribute 1 3 and 4 through the parentheses: 1 3 (9x) − 1 3 (15) + 4(x) + 4(1 2 ) 2. Find each product: 3x − 5 + 4x + 2 3. Combine like terms: What should Ranger write for step 3?
