Question $4$

Consider the basic feasible solution associated with the following set of equations:

$\backslash$table$[[$Row$,$z$,x_1,x_2,x_3,x_4,x_5,x_6,x_7,$RHS$],[0,1,0,0,-5,12,0,0,8,24],[1,0,0,0,3,1,0,1,2,32],[2,0,0,0,1,2,1,0,-1,10],[3,0,1,0,2,0,0,0,4,6],[4,0,0,1,-1,2,0,0,2,12]]$

Suppose you visit this basic feasible solution in the process of solving a maximization linear program by the simplex algorithm. What variable would you enter on the next step?

$x_1$

$x_2$
