(1 point) Use the two-phase simplex method to

(1 point) Use the two-phase simplex method to minimize z = xy + 2x2 + x3 subject to 4x1 X2 3x2 X1 2x3 + 6x3 + 5x3 0 x2 > 0 X3 > 0 If there are no solutions, enter None for z. z = none For the minimum value, enter the values of x1, x2, and x3 in the spaces provided. If there are no solutions, you may leave these answers blank. Xi = 0 X2 = 3 X3 = 1 caution: there can be alternate optimal solutions but unfortunately only one is being graded as correct. If you get the correct value for z and one of the variables, then try looking at your optimal tableau and see if one of the NBV e;'s or S;'s has a 0 in rowo (maybe more than one) and pivot on the one that will become a basic variable while leaving alone your basic variables from X1, X2, X3
