12x What is X?

X is 1.

What is X? Is it like the number time itself x time?

I apologize for the confusion in my previous response. If you have an expression like "12x," it typically means that the number 12 is being multiplied by a variable, which is represented by the letter "x." In this case, the value of x is unknown unless specified. So in the context of "12x," x is a variable that can represent any number.
