- 5arrow_forward3. Consider the following dual problem Minimize Z = 7x₁ + 2x₂ + 5x3 + 4x4 subject to 2x₁ + 4x₂ + 7x3 + x4 ≥ 5 8x₁ + 4x2 + 6x3 + 4x4 ≥ 8 3x₁ + 8x₂ + x3 + 4x4 ≥ 4 and x₁ ≥ 0, x₂ ≥ 0, X3 ≥ 0, X4 ≥ 0. (a) Construct the primal problem corresponding to this problem. (b) Solve the primal problem by the original simplex method (in tabular form) step by step. Identify the complementary basic solution for the dual problem obtained at each iteration. Use the dual simplex method manually to solve the dual problem. Compare the resulting sequence of basic solutions with the complementary basic solutions obtained in part (b). (c)arrow_forwardNeed only a handwritten solution only (not a typed one).arrow_forward
