Write an equation with a variable on both sides of the equal sign that has infinitely many solutions. Solve the equation and explain why it has an infinite number of solutions.

Okay so that is the question, I know it's already on Jiskha but I need it to be explained more. How would I know that a equation has infinite solutions.

x=x

What is the answer to this? Does it have a single answer? Or an infinite number of answers?
That's the things I don't get, I don't know how to solve that. All I think I know is that the problem is basically 1=1.
