Find the equilibrium amount of Tc-GSA in the blood and liver.

Let’s suppose 2.5 mg of glactosyl human serum (Tc-GSA) is injected into the bloodstream. Let B and L be the amount of Tc-GSA in the blood and liver, respectively. The quantities B and L are related by: 1.8 = B + L dB/dt = -0.06B + 0.03L and dL/dt = 0.06B - 0.03L. At equilibrium, the quantities B and L are constant.
