Solve the following LPs using the simplex method (use both the Big-M Method and the Two-Phase Method to verify that they yield the same conclusion). Comment on whether the problem is feasible or not. - If the problem is feasible, then comment on whether the optimal objective function value is bounded or unbounded. - If the problem is feasible and the optimal objective function value is unbounded, then find a direction of unboundedness. - If the problem is feasible and the optimal objective function value is bounded, then comment on whether the optimal solution is unique or there are multiple optimal solutions. maxs.t.3x1+4x22x1+x22x1+3x24x1,x20
