Two lenses are placed on the x-axis. The first lens is a diverging lens with focal length 12 cm placed at x = -1 cm. The second lens is a diverging lens with focal length 2 cm placed at x = 7 cm. If an object is placed at x = -18 cm, what is the position of the image, image type (virtual or real), and magnification of the image?
