Final answer:
X could be any type of real number: an integer, a whole number, a natural number, or an irrational number, since all are part of the set of real numbers.
Step-by-step explanation:
The value of X could be an integer, a whole number, or a natural number since all these are subsets of real numbers. However, without more context, it is not possible to determine whether X is an irrational number because irrational numbers are also a subset of real numbers, but not all real numbers are irrational. In other words, X can be any type of real number: an integer (which includes negative numbers, zero, and positive numbers), a whole number (which starts from zero and includes positive numbers), a natural number (which includes positive numbers starting from 1), or an irrational number (which cannot be expressed as a simple fraction).
