consider the linear programming max z=X1 S.t -X1+x2<2 x1+x2<8 -x1+x2>-4 X1+X2>0

[i]state the above in cannonical form [ii]solve by simplex method

[iii]solve geometrical and trace the simplex procedures graphically [iv] suppose that the objective function is changed to z=X1 + cX2 graphical determine the value of c for which the Solution found in part (b) and (c) remain optimal (v) graphically determine the Shadow price Corresponding to the third constraint
