A tank of water holding 528 kL of water begins to empty at a rate of 10 kL/min. At the same time, another tank, which is empty, begins to fill at a rate of 14 kL/min. Let k represent the number of kiloliters of water and let t represent time in minutes. The system models this situation.

How long will it take for the tanks to hold equal amounts of water, and how much water will that be?

k = 528 – 10t
k = 14t
It will take ___ minutes for both tanks to hold equal amounts of water. They will each hold ___ kiloliters.
