Interesting. Do you have any details on this? It seems like it would be hard to express system of linear inequalities as a finite system of linear equations.

Thanks,

There's a linear [1] reduction from one problem to the other and vice versa.

[1] The transformation itself is a linear function, and it takes O(n) time, too.
