To help you to learn the subject better, I can give you the reference to my lesson on the Linear Programming method.  It is
    - Solving minimax problems by the Linear Programming method
in this site.

Read it --- you will be in much more advanced position then to better understand the method.

After reading my lesson, try solve your problem again.

Post then your updated results to the forum - I will check it here and will give you my feedback.


Happy learning (!)
