Selecting a Leaving Basic Variable | |
The entering basic variable is:
The leaving basic variable is: Why? Choose the basic variable that reaches zero first as the entering basic variable () is increased (watch increase). |

when . | |
Since the coefficient of is negative in equation (2), will never reach zero, no matter how far is increased. Therefore, is the leaving basic variable. |
