Lenses Problem
In the figure are shown two converging lenses with x2 = 1 m. The lens on the left (Lens 1) has a focal length of 0.25 m while the one on the right (Lens 2) has a focal length of 0.2 m. An object 3.9 cm high is located x1 = 0.397 m to the left of Lens 1.

(a) Consider the image of the object formed by Lens 1. Give its distance as measured from Lens 1 and the image height.
Distance = m
SO i was trying to use the thins line equation which is 1/ o + 1/f = 1/I but i don't know what numbers to plug in
