Two groups of volunteers are cleaning up the football stadium after the Homecoming game.
Volunteers from the Band Booster Club have already cleaned 3 rows of bleachers and will
continue to clean at a rate of 2 rows per minute. The leadership class has completed 6 rows
and will continue working at 1 row per minute. Once the two groups get to the point where
they have cleaned the same number of rows, they will take a break and decide how to split
up the remaining work. How many rows will each group have cleaned by then?
