Question: 5. For the linear programming problem of Minimizing z=-6x + 2x2 - 9x3 +12x4 + 8x5 subject to x + 6x2 - 5x3 + 2x4

5. For the linear programming problem of Minimizing z=-6x + 2x2 - 9x3 +12x4 + 8x5 subject to x + 6x2 - 5x3 + 2x4 - 7x5 = 15 -XL - 4x2 + 3x3 - X4 + 5x5 25 X1,42,43,44,45 > 0 - show, using the formulas in this section, that x2 and xs can serve as basic vari- ables in an optimal solution. What is this optimal solution point and the mini- mum of z
