Mаximize Z = 4 x₁ - 5 x₂ subject tо x₁ + x₂ + x3 = 10 x₁ - x₂ + x4 = 6 x₁≥0, x₂≥0, x3 ≥0, x4 ≥0 Sоlve this prоblem using the Simplex Method. (а) Find the optimаl objective function value Z*. (You can only input the value. No need to justify) (b) At the final solution, which are nonbasic variables? (You can only input the value. No need to justify)
