certain basic feasible solution. In our case we substitute 0 for the variables x₁ and x₂ from the right-hand side, and without calculation we see that x₃ = 2, x₄ = 4, x₅ = 4. This feasible solution is indeed basic with S= {3, 4, 5}. The variables x₃, x₄, x₅ from the left-hand side are basic and the
