Tank A has 35 gallons of water and is filling up at a rate of 5 gallons per minute,
Tank B has 100 gallons of water and is
draining at a rate of 8 gallons per minute,
Solve the following system of equations,
In how many minutes will the tanks
contain the same amount of water, and
how much water will that be?
Sy = 35+ 5x
y = 100 - 8x
