a Simplex

Remember that in Phase I of solving a non-standard problem, the indicator row is NOT the bottom (objective) row. Instead, step NS-3 demands that we look for the most negative right-side number above the objective row. In our current problem, there is a tie for most-negative right-side number. It does not matter which "-12" we pick, here, but your professor chose the "-12" in row 3. If we had chosen the other "-12", SIMPLEX METHOD would have still led us to a correct solution.
