When making an account statement, there are two columns, one is the Debit Side and the other is the Credit Side. Debit side means an increase in the Assets, expenses or Revenues. Whereas credit side means an increase in the liability, or equity of the company.
In this case, Debit side has an amount of 1900 and Credit side has an amount of 1100. The balance of the account would be 1900 - 1100 = 800 Debit.
It can be like:
Debit | Credit
------------------------------------------
1900 | 1100
------------------------------------------
Balance: 800
