{:("Column A", 7x + 3y = 12","3x + 7y = 8 , "Column B"),(x-y,,1):}

By using LPP maximize z= 17.5x+7y subject to the constraints x +3y leq 12, 3x +y leq 12 and x,y geq 0

Determine graphically the minimum value of the objective function: Z = -50x + 20y subject to the constraints: 2x - y ge -5, 3x + y ge 3, 2x - 3y le 12, x, y ge 0 .

Minimise Z = 3x + 5y such that x + 3y ge 3, x + y ge 12, x , y ge 0

Solve the system: x + y - 2z = 0, 2x - 3y + z = 0, 3x - 7y + 10z = 0, 6x - 9y + 10z = 0.

If the system of equations 2x-3y+5z=12, 3x_y+pz=q and x-7y+8z-17 is consistent, then which of the following is not true?

4x -5y-11z=12,. x-3y+z=1 2x + 3y-7z = 2

Solve the following LPP graphically : Maximize : Z = 10x + 12y Subject to the constraints 2x + 3y le 30,3x +y le 17,x, y ge 0 .
