please solve question 2

Group A Use the Big M method to solve the following LPs: 1 min z = 4x + 4x2 + x3 St. x + x2 + x 52 2x + x2 33 2x1 + x2 + 3x3 2 3 X1, X2, X3 20 2 min z = 2x1 + 3x2 s.t. 2x1 + x2 > 4 X-X22 -1 x1, x2 = 0 3 max z = 3x1 + x2 s.t. x1 + x2 2 3 2x1 + x2 = 4 x1 + x2 = 3 X1, X220 4.13 The Two-Phase Simplex Meth When a basic feasible solution is no be used as an alternative to the Big tificial variables to the same constrain to the original LP by solving the Pha minimize the sum of all artificial vari original LP's objective function and The following steps describe the the two-phase simplex are identical *This section covers topics that may be omitte 170
