Translate the problem situation to a system of equations. Do not attempt to solve.The sum of two numbers is 22. Five times the smaller number minus twice the larger number is 264. What are the numbers? (Let x represent the smaller number and y represent the larger number.)
A. x - y = 22, 5x + 2y = 264 B. x + y = 22, 2x - 5y = 264 C. x + y = 22, 5x - 2y = 264 D. x + y = 22, 5x + 2y = 264
