Answer Details
The accounting concept that supports the application of double entry book-keeping is the dual aspect concept. This concept states that every transaction has two aspects - a debit and a credit - which must be recorded in equal amounts. This ensures that the accounting equation (assets = liabilities + equity) is always in balance. In other words, every transaction has an equal and opposite effect on the accounting equation, which helps to maintain the integrity of the financial statements. The dual aspect concept is also known as the duality principle or the double entry system, and it forms the foundation of modern accounting practice.
