1. Two well-mixed tanks are hooked up so that water with 2 pounds of salt per gallon flows into the first tank, well - mixed water flows out of the second tank, water flows from the first tank to the second tank, and water flows from the second tank to the first tank. All flows are constant. Determine how much water is in each of the two tanks, given if x is the amount of salt in the first tank and y is the amount of salt in the second tank then 3x 2x - 3y. The answer should -x + y + 30 and 6y' be 45 gallons in the first tank and 30 gallons in the second tank. =

Question
1. Two well-mixed tanks are hooked up so that water
with 2 pounds of salt per gallon flows into the first tank,
well - mixed water flows out of the second tank, water
flows from the first tank to the second tank, and water
flows from the second tank to the first tank. All flows are
constant. Determine how much water is in each of the
two tanks, given if x is the amount of salt in the first tank
and y is the amount of salt in the second tank then 3x
= -x + y + 30 and 6y' 2x - 3y. The answer should
be 45 gallons in the first tank and 30 gallons in the
second tank.
