Every LP can be brought into ``standard form'' through the following transformations:

- an inequality constraint:
can be converted into an equality one, through the introduction of a

*slack (excess)*variable : - A variable with sign restriction can substituted by with
- Finally, a
*urs*variable can be substituted by with .

* You can get a clearer idea about how the above transformation
works, by having it applied to your own examples. To interpret the
obtained results, notice that the final outcome is presented
in a "tableau" format. *
