Independent equation

Imagine that you have two toys, a car and a train. These toys are both independent because they have their own unique functions and don't rely on each other to work.

Now, let's say you have two mathematical equations. These equations are also independent because they can stand on their own and don't need any other equations to work.

For example, the equation "2 + 3 = 5" is independent because it's complete and doesn't need any additional equations to solve it.

So, an independent equation is like a toy that can work on its own without needing any help from other toys or equations.
