Note on x in mathematics :

As we know that

The letter "x" is often used in algebra to mean a value that is not yet known.

It is also called a "variable" or sometimes an "unknown".

For example:

x + 2 = 7,

Here, x is a variable, but we can work out its value if we try.

A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.
