Please use the big M method to solve the following linear
program. Write down all tableau, note basic variables and nonbasic
variables. Use slack and artificial variables. Construct your
tableau iterations using the standard form of the program. For
example first line z+2x1-2x2+2x3=0. If possible, STATE THE OPTIMAL
SOLUTION AND THE OPTIMAL VALUE. Otherwise state why you cannot find
them.

Consider the linear program: 1, 2,3, 4,25 2 0 Perform a Phase-I calculation to determine an initial basic feasible solution. Write down the initial simplex tableau for the Phase-I problem and the resulting initial simplex tableau for the Phase II problem. The initial simplex tableau must have the objective function expressed in terms of the nonbasic variables. You may use software to solve the Phase-I problem.
