Question: 4 show that the three inequalities have no solution x...

Question details

4. Show that the three inequalities have no solution x, y, z with x, y, z 2 0 by using our two phase method. In addition, try to show infeasibility by finding a (positive) linear combination of the three inequalities which provides an obvious contradiction to r, y,z 2 0. The magic coefficients can be found in the final w row as the negative of the coefficients of the three slack variables you introduced
