Practice Problem on Lenses in Combination

Two lenses are placed on the x-axis. The first lens is a converging lens with focal length 15 cm placed at x = -5 cm. The second lens is a converging lens with focal length 12 cm placed at x = 9 cm. If an object is placed at x = -11 cm, what is the position of the image, image type (virtual or real), and magnification of the image?

ANSWER = (x = 33.00 cm, real, m = -1.67)
