# Simplex method - infeasible basic variables

I am working on an optimization problem right now, and I am using the simplex method on the initial tableau. At first, the basic variables are all non-negative and are equal to the slack variables. One of the reducing cost coefficients were positive, so I did a pivot operation.

Right now, none of the reducing cost coefficients are negative, so there is no more steps I can take as far as the simplex method goes. However, two of the four basic variables are negative (if I let the non-basic variables be zero, the right hand side of the equation is a negative constant).

How would I solve such a problem? I know it's a bit hard without seeing numbers, but I this is a problem set I have to turn in and I'd like to know the tecnique behind it.

Thank you
