    f(x)=80x_2x^2-xy-3y^2+100y subject to x+Y=12 by Lagrange method.


    g(x,y)=80x-2x^2-xy-3y^2+100y +L( x+Y-12)

    L is the Lagrange undetermined multiplier to be determined. Take partial derivative of g wrt x and y and equate them to 0.

    wrt x gives


    wrt y gives


    I am unable to solve it as we do not proper relationship. Is it x+y or xy=12?
