Rent expired during year, 9300. Do I debit or credit on an adjusted entrie

Rent expired means that you used rent that was prepaid during the period. You will have a debit and a credit. Debits = Credits is very basic accounting, not a 301 level accounting course.

Your debit will be to Rent Expense because you used the rent.
Your Credit will be to Prepaid Rent because you used part of the rent that was paid for in advance.
