A Solve graphically for the optimal solution.
B How does one know that although x1=5, x2=3 is a feasible solution for the constraints, it will never be the optimal solution no matter what objective function is imposed?
The process of solving a linear programming problem graphically is explained and illustrated by an example.
The solution is in a PDF file.
