You are using the simplex method to solve the following linear programming problem.Maximize Z = 6x1 + 5x2 - x3 + 4x4,subject to 3x1 + 2x2 - 3x3 + x4 ≤ 120 3x1 + 3x2 + x3 + 3x4 ≤ 180 and x1 ≥ 0,x2 ≥ 0,x3 ≥ 0,x4 ≥ 0.You have obtained the following final simplex tableau where x5 and x6 are the slack variables for the respective constraints. 
Use the fundamental insight presented in Sec.5.3 of the textbook to identify Z*, 
,and 
.
