I know how to solve recurrence relations so I don't need help but what is confusing me is to solve simultaneous recurrence relations. How can I start?

Thank you for your time and any type of help you can provide me!

This is only a fictif example, so if anyone could provide me a solution, I will try to apply it to the real problem that I have to solve.
