Subject: Modal Logic Chellas Problem Two

These problems are featured in Chellas' Introduction to Modal Logic and I have absolutely no idea how to solve this or even approach it. If anyone has any idea how to perhaps help me, I would greatly appreciate it. I wish to solve problems 9.31 as shown in the attachments. All files that are needed are attached. Please let me know asap!
Thanks

Sorry, I am not that expert to help. By the way, I've started to study Chellas's book about modal logic but I found it really complicated. So I have switched to "A New Introduction to Modal Logic" by Hughes & Cresswell.
