In the problem Z = 3x₁ + 2x₂ Subject to 2x₁ + x₂ ≤ 20 ---(i) x₁ ≤ 10 ---(ii) x₁, x₂ ≥ 0 ---(iii) constraint (iii) is kno
From the definition, using formula we get non-negativity constraint. Calculation gives this directly, check steps: apply rule, substitute values, simplify to get non-negativity constraint.
