An object is placed 31.5 cm from a +5.0-D lens. A spherical mirror with focal length 25 cm is placed 75 cm behind the lens. Note that the mirror reflects light back through the lens.

Find the distance from original object to the final image, measured from the object toward the lens. Enter negative value if the object is between the image and the mirror and positive value otherwise.
