OPERATING RESEARCH + X6 00 + X7 *3. Consider the

+ X6 00 + X7 *3. Consider the following system of equations: X; + 2x2 3x3 + 5x4 + Xg = 4 5xi 2x2 + 6x4 = 2x + 3x2 - 2x3 + 3x4 = 3 -X1 + x3 - 2x4 + x3 = 0 X1, X2, ... dg 20 Let X5, X6, and xg be a given initial basic feasible solution. Suppose that x; becomes basic. Which of the given basic variables must become nonbasic at zero level to guarantee that all the variables remain nonnegative, and what is the value of xy in the new solution? Repeat this procedure for X2, X3, and X4
