Let me help you:

Although your question has not been uploaded completely, as long as you remember the rules of the middle school lens imaging question, you can get it right with ordinary questions.

I will send you two pictures for you to compare and see if you can solve the problem.

I hope it can be helpful to you and wish you good progress in your studies!
