How to know if an equation has no solutions or infinitely many solutions? And what do we do with this? Watch to find out.

Usually, when we solve linear equations, we end up getting one single solution. That solution could be any type of number, but it's still ONE solution. But in some special cases, we sometimes end up with no solutions (the null set), or infinitely many solutions (the identity). How do we know if this happens? And what does it mean if this happens?
