## Homework Statement

An object is 1.75 m to the left of a lens of focal length 0.62 m. A second lens of focal length -2.7 m is 0.52 m to the right of the first lens. Find the distance between the object and the final image formed by the second lens.

## Homework Equations

(1/x1)+(1/image)= (1/focal point 1)

(1/x2 - image) + (1/x3)= (1/focal point 2)

## The Attempt at a Solution

i use

x1=1.85

focal 1 = .62

solve for image in first equation

then use

x2=.52

focal 2 = -2.7

use the second equation and solve for x3

and get .526 m

i think I am following the steps right, but keep getting the wrong answer. any help would be great

thanks!
