What is the solution for question 15, chapter 4.17, page 214 of Winston W. Operations Research. Applications and algorithms, 4ed 2003?

Consider a maximization problem with the optimal tableau in Table 73. The optimal solution to this LP is z = 10, x3 = 3, x4 = 5, x1 = x2 = 0. Determine the second-best bfs to this LP. (Hint: Show that the second-best solution must be a bfs that is one pivot away from the optimal solution.)
