5. Use the simplex method with the tableau to solve the following LP. Report the value of all the variables of an optimal solution, if there is an optimal solution. If there is no optimal solution, report why. [15 points) maxx s.t. 5.x, 54 6x, 58 3x, 33 x 20
(3) Kyle gave Cartman the tableau of a max-LP to solve using the simplex method. The LP had two variables (x1, 22) and two < constraints. Cartman decided to play a joke on Kyle, so he (a) changed the coefficient of zi in the first constraint from 6 to 9, and (b) solved the LP as a min-LP With these modifications, Cartman got the following"optimal" tableau after performing a single pivot. Find the correct optimal tableau that Kyle should have...
1. Apply the simplex method to solve the following LP. Use the tableau format. You should show that you know the simplex method, standard forms and optimality criteria. Don't worry about arithmetic and do not do more than 2 iterations. Comment on an optimal solution. maximize subject to 21 + 2x2 – x1 + x2 = 2 —2x1 + x2 <1 x1, x2 > 0
