RATES
Pump Expected,
Leak,
Pump Plus Leak,
The rates are additive for the two agents working simultaneously. The choice of giving the leak a negative sign or simply to subtract the absolute value depends on how you want to handle this; just understand that the pump and the leak are not in the same one-dimensional direction.
You can take u as a positive number; your way of handling the sum of the rates could be either of these:
pump + leak = both together, and "leak" rate is a negative number.
OR
pump-leak=BothTogether, and "leak" rate is a positive number.
LCD is 14u
The leak by itself can empty the tank in 14 hours.
