    3. The attempt at a solution

    I have substituted x_2 with y_2=x_2-4/3. However, I run into trouble when I attempt to determine the feasible solution.

    First iteration:

    s_1 and s_2 are my slack variables. I am not sure how to determine the feasible starting solution. Furthermore, no matter which variable I choose as the non basic variables, their coefficient are always non negative. (But the equation hasn't reached optimality yet)

    Thanks in advanced.
