(Cоntinued frоm Q2) The secоnd phаse of simplex is being performed on аn LP with 8 vаriables and 3 constraints. We denote this LP (LP2).In the current iteration of simplex, we form the LP in canonical form using the basis , as follows: Suppose instead of the answers you wrote in 3(b)(ii) and (b)(iii), you chose to have enter the basis and leave. What are the mistake(s) with this choice? How will this affect your next iteration of simplex?
