Modify the objective function in the Excel solver example considered in the lecture to the following: z=2x1 +3x2+2x3. Report the optimal solution you obtain: x1= x2= x3= Z= In Excel, change the objective function back to z=4x1+3x2+5x3. Modify the right-hand sides of the constraints to the following: 6;6;10. Report the optimal solution you obtain: x1= x2= x3= Z= Modify the objective function in the Excel solver example considered in the lecture to the following: z=2x1 +3x2+2x3.
