5. (7 points) In the figure below, assume that no solution flows out of the system from tank B, only 1 L/ min flows from A into B, and only 4 L/ min of brine flows into the system at tank A, other data being the same. Determine the mass of salt in each tank at time t≥0 A 6 L/min 0.2 kg/L 3 L/min x(t) 100 L CourseSmar 4 L/min x(0) = 0 kg 1 L/min B y(t) 100 L y(0) = 20 kg 2 L/min Write the system of differential equations with the initial conditions, but do not solve the system.
