Thank you! I finally found a video on the conjugate foci method and now I completely understand!

Thank you so much I understand now!! The two solutions are the same so object distance and image distance must be the same!!!

This is the solution but I do not understand??? How could they just assume the object distance equals 2f? No magnification is given here. We know the candle produces a real image and the distance is limited, so that means it must be somewhere between the principal focus, the center of curvature...
