4. Consider the closed two-tank system where mixed brine flows from tank 1 into tank 2 and from tank 2 into tank 1 at the flow rate of r gallons per minute (see the following figure). The initial amounts x(0) = To and y(0)= yo of salt in the two tanks are given, as are their volumes Vi and V2 gallons. t
