What are the journal entries for accrual accounting and cash accounting for an invoice and a payment?

How do I indicate what goes into to the debits column and what goes into the credits column?

Hi, Kindly let me know the journal entry required to pass in case of the below scenario. I know this is simple but wanted a clarification. What entry would be passed in case an invoice is paid against a particular purchase order for the purchases made for 500$.

I need to make the following journal entry, how would I go about doing it? Thanks! My company borrowed cash from a bank, 500,000 with an interest rate of 6% not due in 4 years.
