Extracted text: Let A be the point with coordinates (1, -3, 3), let B be the point with coordinates (3, -1, -3), let C be the midpoint of the line segment AB, let D be the point with coordinates (1,0,0), and let E be the point with coordinates (0,1,0). Let II be the plane passing through the three points C,D,E. Suppose that the line x-Dy%3Dz intersects the plane II at the point P. Write down the first coordinate of P.
