Sure, so say $10,000 worth of expense relating to salaries has been incurred but not yet paid. The first JE would be :
DR. Expense
CR. Salaries Payable
And then after you pay the salaries:
DR. Salaries Payable
CR Cash
So the first entry is made to increase accounts payable which is a liability account. So once you pay the salaries, AP decreases by being debited, and cash also decreases by being credited.
For the next example lets say you get cash that has not been earned yet.
DR. Cash
CR. Unearned Revenue
Then when you earn the revenue
DR. Unearned Revenue
CR. Revenue
Unearned revenue is a liability account so it increased at original entry, but decreases once you earn it. Hopefully that helps.
