Web(Solved): Solve the linear programming problem using the simplex method. MaximizesubjecttoP=9x1 ... WebThis is an important result since it implies that the dual may be solved instead of the primal whenever there are computational advantages. Let us further emphasize the implications of solving these problems by the simplex method. The opti-mality conditions of the simplex method require that the reduced costs of basic variables be zero. Hence,
