This has already been answered, more than once.
Elimination Method for this is very uncomplicated.


system%283A%2B5B=9%2C12A%2B2B=9%29

system%284%283A%2B5B%29=4%2A9%2C12A%2B2B=9%29

system%2812A%2B20B=36%2C12A%2B2B=9%29

E1-E2
%2812A%2B20B%29-%2812A%2B2B%29=36-9
18B=27
2B=3
highlight%28B=1%261%2F2%29-------------hours for one session of plan B.


And you should know how to find A.
