Hi! could any help me please, thank you.

1.An object is placed 17.8 cm from a first converging lens of focal length 13 cm. A second converging lens with focal length 24 cm is placed 10 cm to the right of the first converging lens. (Take the direction to the right to be positive.)

(a) Find the position q1 of the image formed by the first converging lens.

144

and also could you show me how to calculate for this? Thank again

1/28+ 1/v = 1/(-14)
