3. In Example 3.4-1, identify the starting tableau for each of the following (independent)

cases, and develop the associated z-row after substituting out all the artificial variables:

*

(a) The third constraint is Xl + 2X2 ;::: 4.

*

(b) The second constraint is 4XI + 3X2 :::::: 6.

(c) The second constraint is 4XI + 3X2 = 6.

(d) The objective function is to maximize z = 4xI + x2'
