Write a system of equations to describe the situation below, solve using substitution, and fill in the blanks
Mike is training for a triathlon and needs to swim a certain distance for today's workout. If he swims at
the rec center pool, he will complete a 156-yard warmup and then swim laps in a lane that is 48 yards
long. If Mike swims at the indoor pool at his gym, he will complete a 166-yard warmup, plus a main set
that consists of 38 yards per lap. If Mike swims the correct number of laps, he can complete the same
distance in either pool. How many laps will that take? How long will Mike's workout be in total?
If Mike swims___
