solve by the elimination method

Solve: 3x - 4y = 20 (i) 5x + 6y = 8 (ii) Multiply (i) by 3 and (ii) by 2: Adding the two, 19x = 76 Substituting x = 4 in (ii), we get 5(4) + 6y = 8 6y = 8 - 20 6y = -12 y = -2 The solution is x = 4 and y = -2..

Method of Elimination - Solve: 3x - 4y = 20 (i) 5x + 6y = 8 (ii) Multiply (i) by 3 and (ii) by 2: Adding the two, 19x = 76 Substituting x = 4 in (ii), we get 5(4) + 6y = 8 6y = 8 - 20 6y = -12 y = ..

Use the elimination method to solve the linear system. 6 x + 5 y = 49 5 y = 41 - 4 x => (4, 5) or (- 4, - 5) or (- 4, 5) or (4, - 5)..

Solve the system using Elimination method. w + 4 x - z = 3 - w + 11 x + y + z = 64 w + y = 16 x - y = - 3 => (23, 16, 1, 25) or (9, 16, 1, 22) or (64, 4, 7, 22) or (9, 4, 7, 22)..

Solve the system of equations using Gausssian elimination method. x + y = z 7 x - z = y - y = z => (8, 0, 7) or (1, 1, 7) or (7, 1, 8) or (0, 0, 0)..

Solve the system of equations by Gauss elimination method: x + 2 y = 4, 3 x + 4 y = 5, and 2 x + 3 y = 4 => x = 2, y = -5, z = 0 or x = 6, y = -7, z = 1 or x = -3, y = 6, z = 0 or No solution..

Solve the system using the elimination method: x 1 6 + y 1 5 = 35 x 3 - z 1 6 = - 1 5 x - y 3 = 80 => (48, 480, 272) or (51, 480, 240) or (51, 570, 272) or (48, 570, 240)..

Use Elimination method to solve the system. x - 42 y = 84 y + z = 7 8 x - z = 328 => (7, - 1, 8) or (42, - 1, 8) or (42, 8, 7) or (8, - 1, 42)..

Use Elimination method to solve the system. 11 x - y = 11 y - z = 11 x + 12 z = 2 => (2, 10, 0) or (0, 11, 0) or (22, 144, - 133) or (2, 11, 0)..

Graphical Method of Solution of a Linear Programming Problem - So far we have learnt how to construct a mathematical model for a linear programming problem. If we can find the values of the decision variables x 1 , x 2 , x 3 , ..... x n , which can optimise (maximize or minimize) the obje..
