A group of college students are going to a lake house for the weekend and plan on
renting small cars and large cars to make the trip. Each small car can hold 5 people
and each large car can hold 7 people. The students rented 2 more small cars than
large cars, which altogether can hold 46 people. Write a system of equations that
could be used to determine the number of small cars rented and the number of large
cars rented.
