The equations that must be solved for maximum or minimum values of a differentiable function wequalsf(x, y,z) subject to two constraints g(x, y,z)equals0 and h(x, y,z)equals0, where g and h are also differentiable, are h, g(x, y,z)equals0, and h(x, y,z)equals0, where lambda and mu (the lagrange multipliers) are real numbers. use this result to find the point closest to the origin in the line of intersection l of the planes x plus 2 z equals 24 and x plus y equals 12.
