use the Big M method to solve the following LPs: 2 max z = x1 + x2 s.t. 2x1 + x2 > 3 3x1 + x2 < 3.5 X1 + x2 < 1 X1, X2 > 0
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 following linear program: 2x3 max z= –2x1 + s.t. + -x1 21 > 0, 2x2 - 2x2 +...

Note that problems 2, 3, and 4, require you to use the two-phase simplex method. For each iteration, in addition to other calculations, clearly show the following: the dictionary, entering variable, minimum ratio, and the leaving variable. Note that we employ Dantzig's...
