convert the inequality 4x₂ -x₁ ≤ 13 we introduce a new variable x₃, together with the nonnegativity constraint x₃ ≥ 0, and we replace the considered inequality by the equation -x₁ + 4x₂ + x₃ = 13. The additional variable(slack variable) x₃, which won’t appear anywhere else in the transformed linear
