Melvin plays tennis and swim for a total of 110 minutes every day. He plays tennis for 40 minutes longer than he swims. Write a pair of linear equations to show the relationship between the number of minutes Melvin plays tennis (x) and the number of minutes he swims (y) every day. How much time does Melvin spend swimming every day? Show your work. Is it possible for Melvin to have spent 70 minutes playing tennis if he plays and swims for a total of exactly 110 minutes and plays tennis for 40 minutes longer than he swims? Explain your reasoning
