How do the 3 statements link together?

''To tie the statements together, Net Income from the Income Statement flows into Shareholders’ Equity on the Balance Sheet, and into the top line of the Cash Flow Statement.

Changes to Balance Sheet items appear as working capital changes on the Cash Flow Statement, and investing and financing activities affect Balance Sheet items such as PP&E, Debt, and Shareholders’ Equity. The Cash and Shareholders’ Equity items on the Balance Sheet act as “plugs,” with Cash flowing in from the final line on the Cash Flow Statement.”
