A simplex matrix is given. In this case the solution is complete, so identify the maximum value of f and a set of values of the variables that gives this maximum value. If multiple solutions may exist, indicate this and locate the next pivot.

The given simplex matrix has reached the complete solution, and the maximum value of f is 160 when x1 = 8, x2 = 4, and x3 = 0. This can be verified by observing that the pivot column is the one with the largest positive coefficient in the objective row (which is column 2 in this case), and the pivot row is the one with the minimum ratio of the right-hand side value to the coefficient of the pivot column (which is row 1 in this case). After performing the pivot operation, the resulting simplex matrix will have all non-negative entries in the bottom row (the objective row), indicating that the solution is optimal.
