What Does It Mean When an Inequality is a Contradiction or Has No Solution?

Note:

Can an inequality have no solution? You bet it can! An inequality has no solution will always give you a contradiction, no matter what value you plug in for the variable. Watch this tutorial, and then try to make your own inequality with no solution!
