Write a system of equations to describe the situation below, solve using substitution, and fill in the blanks.
Oliver 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 244-yard warmup and then swim laps in a
lane that is 28 yards long. If Oliver swims at the indoor pool at his gym, he will complete a
246-yard warmup, plus a main set that consists of 26 yards per lap. If Oliver swims the
correct number of laps, he can complete the same distance in either pool. How many laps will
that take? How long will Oliver's workout be in total?
If Oliver swims
laps at either pool, he can complete a total workout of
yards.
