Final answer:
Two possible solutions are: (x = 2, y = 2) and (x = 3, y = 5).
Step-by-step explanation:
Since the Junior-Senior Prom Committee must consist of at least 2 juniors and 2 seniors, we can assign values to x and y as follows:
Case 1: x = 2, y = 2
This means that there are 2 juniors and 2 seniors on the committee.
Case 2: x = 3, y = 5
This means that there are 3 juniors and 5 seniors on the committee.
