A and B, the amount of time of each plan 

                  Plan A           Plan B     total time hrs.

FRIDAY             3                   5             9

SATURDAY          12                   2             9

Accounting for the time quantities in both days' workouts
system%283A%2B5B=9%2C12A%2B2B=9%29
This should be clear and how to solve should be very routine and common. Elimination Method may be best.
