In Problem 1 suppose that time is measured in days, that the decay constants are k₁ = 20.138629 and k₂ = 20.004951, and that x₀ = 20. Use a graphing utility to obtain the graphs of the solutions x(t), y(t), and z(t) on the same set of coordinate axes. Use the graphs to approximate the half-lives of substances X and Y.
