Two thin convex lenses of focal lengths ...

Two thin convex lenses of focal lengths `f_(1)` and `f_(2)` are separated by a horizontal distance d (where`dltf_(1)`,`dltf_(2)`) and their centres are displaced by a vertical separation `triangle` as shown in the fig.
Taking the origin of coordinates O, at the centre of the first lens the x and y coordinates of the focal point of this lens system, for a parallel beam of rays coming form the left, are given by: `

In the figure- it is shown,the focal length f of the two thin convex lenses is the same. They are separated by a horizontal distance 3f and their optical axes are displaced by a vertical separation 'd'(d lt lt f) as shown. Taking the origin of coordinates O at the centre of the first lens , find the x and y coordinates of the point where aparallel beam of rays coming from the left finally gets focussed ? ((5f, 2d)]
