Currently you'd need to reformulate to standard computational form yourself.
I hope to add a basiic modelling language, and make the algorithm competitive, one day.

So what do I do next after converting to standard computational form?

maximize z = x1 + 2x2 - x3
where
slack1 + 2x1 + 2x2 + x3 = 14
slack2 + 4x1 + 2x2 + 3x3 = 28
slack3 + 2x1 + 5x2 + 5x3 = 30

Side note:
You might be able to use my library. But it's still in beta and rather heavy.

Example:

// Input

var type = "maximize",
 z = "x1 + 2x2 - x3",
 constraints = [ 
    "2x1 + 2x2 + x3 <= 14", 
    "4x1 + 2x2 + 3x3 <= 28", 
    "2x1 + 5x2 + 5x3 <= 30" 
]
Input.parse( type, z, constraints).convertToStandardForm().toString();

// outputs
"maximize z = x1 + 2x2 - x3, where slack1 + 2x1 + 2x2 + x3 = 14, slack2 + 4x1 + 2x2 + 3x3 = 28, slack3 + 2x1 + 5x2 + 5x3 = 30"

You build an object, and set number of variables, number of constraints, the dense A matrix, b vector, c vector, and x lower and upper bounds. Check out the TSP example.

Your code looks like it could be configured to work with it. It seems you are using the full simplex method with rational numbers, judging by the output?
