Why are variables useful in algebra?

My answer:
Variables are useful in algebra because they detemine an answer that anyone is trying to get to.

Variables can represent a single number or a whole sub-equation. they make advanced math possible. You can call "the speed of the car" A, for example. It is much better than writing it all out every time. the higher the math gets the more important the use of variables becomes.

Thank you
