First we define the variables: x = fiction books y = nonfiction books We write the system of equations that best suits the problem. We have then: x + y = 12 2x + 3y = 28 Solving the system: x = 8 y = 4 Answer: x + y = 12 2x + 3y = 28 the number of fiction and nonfiction books on the first list are: 8 fiction books 4 nonfiction books
