method to solve lpp

Use the elimination method to solve the system: 8 x + y = 8 z - 1 x - z = - 1 57 x + 8 = y - 7 z => ( 1 8 , 7, - 7 8 ) or (- 1 8 , 0, 7 8 ) or (- 1 8 , 7, 7 8 ) or ( 1 8 , 0, - 7 8 )..

Use Elimination method to solve the system. 5 x + z = 7 y - 11 x + y = 5 + z 113 x + 6 z = 1 => ( 1 5 , 6 5 , - 18 5 ) or ( 1 5 , 6 5 , 1) or (5 , 5 6 , 0) or ( 1 5 , - 6 5 , 18 5 )..

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 ..

If (x 1 , y 1 ) is the point found in step 4, then x = x 1 , y = y 1 , is the optimal solution of the LPP and Z = ax 1 + by 1 is the optimal value. The above method of solving an LPP is more clear with the following exampl..
