Every linear programming optimization problem may be viewed either from the primal or the dual, this is the principal of duality. Duality develops the relationships between one linear programming problem and another related linear programming problem. For example in economics, if the primal optimization problem deals with production and consumption levels, then the dual of that problem relates to the prices of goods and services. The dual variables in this example can be referred to as shadow prices.

Constructing a Dual:
Construct the Dual for the following maximization problem:
For the problem above, form augmented matrix A. The first two rows represent constraints one and two respectively. The last row represents the objective function.
Note that the original maximization problem had three variables and two constraints.
