(b) Consider the following LP (P) in SEF. Note that (P) is in the form corresponding to the feasible basis B = {4,5}. max -7x1+5x2 subject to -1 1 1 x= -3 20 21, 22, 23, 240 Solve (P) using the Simplex Algorithm, starting with the basis B = {3,4). Show all of your work. If you have a choice between entering or leaving variables select the variable with the smallest index. Stop after three iterations of the Simplex Method even if your solution is not complete.
