The system of checks and balances work by ensuring no single branch of government has more power than the other. An example of this would be that the Judicial branch vetoes executive orders. Another example is the executive branch vetoing legislative branch. Some examples of real-world examples, the legislative branch impeached President Donald Trump. This is a example of check's and balances because the legislative branch is ensuring that the executive branch doesn't overpower the other branches. Another check's and balacnes is that the supreme court is nominated by the president confirmed by the legislative branch.
