Question:

Reconsider Prob. 4.3-6.

Now use the given information and the theory of the simplex method to identify a system of three constraint boundary equations (in x1, x2, x3) whose simultaneous solution must be the optimal solution, without applying the simplex method. Solve this system of equations to find the optimal solution.
