It took Ian three years to collect 20,413 aluminum cans to recycle. In the first year he collected 8,917 cans, and in the second year he collected 7,639 cans. Which equation can be used to find x, the number of cans Ian collected in the third year?

• x = 25,413 - 8,917 - 7,639

• x = 25,413 + 8,917 + 7,639

• 8,917 + 7,639

• 8,917 - 7,639
