please help me with the third question. Thank you

5. Consider the following linear program: (20 pts.) We 2 = A EB subject to: -A +13 5 4 A B 5 4 A + B 3: 6 B E 3 A? B :3 0 (1) Use a ruler to plot the constraints and indicate the feasible region for the LP on a graph paper. (2) Use the comerpoint method to nd the optimal solution and the minimum objective mction value. (Note: The graph paper should be included at the end of your homework submission. (3) Use the simplex method to solve this problem. What are the optimal solution and the optimal objective function value
