method to solve lpp

Use Elimination method to solve the system. 3 x + 4 y + z = 24 2 x - y + 5 z = 18 3 x - 2 y + z = 6 => x = 3, y = 3, z = 3 or x = 3, y = 3, z = - 3 or x = 2, y = 4, z = 3 or x = 3, y = ..

The graphical method of solving an LPP is possible only if there are two decision variables (say x and y). This method is not suitable if there are three or more decision variables. In this case, there is a powerful method called 'simplex metho..

Solve the system using Elimination method. w + x - y - z = 0 - 2 w + x + 4 y + 3 z = 6 3 w - x + 2 z = 4 w + 5 y - 5 z = 1 => (1, 1, 1, 1) or (1, 1, 1, 0) or (0, - 1, 1, 4) or (1, - 1, 0, - 1)..

Solve the following LPP graphically using ISO- profit method. maximize Z =100 + 100y. Subject to the constraints ..

Find the optimal solution in the above problem of decorative item dealer whose objective function is Z = 50x + 18y. In the graph, the corners of the feasible region are O (0, 0), A (0, 80), B(20, 60), C(50, 0) At (0, 0) Z = 0 At (0, 80) Z = 50 (0) + 18(80) = Rs. 1440 At (20, 60), Z = 50 (20) +18 ..
