9. A farmer has 1000 acres of land available for planting corn and wheat. It costs $30 to plant an acre of corn and $20 to plant an acre of wheat. He has a total budget of $22,000 and he wants to spend all of it, and he wants to use all of his acres of land. Let z denote the number of acres of corn and y the number of acres of wheat planted. Set up (do not solve) a system of equations that he could use to determine how many acres of each crop he should plant.
