Central High School had five members on their swim team in 2010.
Over the next several
years, the team increased by an average of 10 members per year.
The same school had 35
members in their chorus in 2010.
The chorus saw an increase of 5 members per year.
Write a system of equations to model this situation, where
x
represents the number of
years since 2010.
