I am confused about correcting a trial balance...

I figured out that cash should be a debit and unearned service revenue should be a credit...

I am stuck on these questions...

1) A payment of $65 for telephone charges was recorded as a debit to Office Expense for $65 and a debit to Cash for $65

2) A payment on account for $206 was credited to Cash for $206 and credited to Accounts Payable for $260

3) A dividend of $575 was debited to Wages Expense for $575 and credited to Cash for $575

You're not really correcting a trial balance. You're correcting individual entries.

We are not here to just answer your homework for you, so do you have any ideas on these? What do you think they should be? And how do you think you should go about correcting them?
