Suppose thay a drug is administered to a person in a single dose, and assume that the drug does not accumulate in body tissue, but is excerted through urine. Denote the amount of drug in the body at time t by x1(t) and in the urine at time t by x2(t). If x1(0)=6 mg and x2(0)=0, can you find a system of differential equations for x1(t) and x2(t) if it takes 20 minutes for the drug to be at one-half of its initial amount in the body?

Question

Suppose thay a drug is administered to a person in a single dose, and assume that the drug does not accumulate in body tissue, but is excerted through urine. Denote the amount of drug in the body at time t by x₁(t) and in the urine at time t by x₂(t). If x₁(0)=6 mg and x₂(0)=0, can you find a system of differential equations for x₁(t) and x₂(t) if it takes 20 minutes for the drug to be at one-half of its initial amount in the body?
