Gregory Library had an overstock of books. After sending 8,342 books to Maxwell Library and 4,102 books to Owen Library, they still had 24,714 books left. Which equation can be used to find b, the number of books Gregory Library had before sending books to the other libraries?

• 8,342 + 4,102 + 24,714 = b

• b – 24,714 – 8,342 = 4,102

• 24,714 + 8,342 – 4,102 = b

• 24,714 = b – 8,342 + 4,102
