I'm not exactly sure how I would fix this if I could get like an example to help me solve this, I would really like that. When I read these I get confused. I haven't done accounting for months so just trying to get back into the mindset is difficult. #4 confuses me the most.

A payment is a credit to cash.

This is a common problem for students you have to adjust the way you think about a cash account or a bank balance

Cash is an asset it's value is reduced by making a payment

The first you adjust for the difference
The second is an item that should be recorded as a purchase of equipment
The third you have to adjust the revenue account
The fifth you have to adjust the balance

What is usual is to have a worksheet with the original balance the correction and the final balance
