Follow the process to find the point on the planes 3x + 3y + z = 18 and y+2z = 40 that is closest to the origin:
Use Lagrange multipliers to find the maximum value of
f(x, y, z) = x^2 + y^2 + z^2,
subject to the constraints: g(x, y, z) = 3x + 3y + z = 18 and h(x, y, z) = y + 2z = 40, by following these steps.
