The 'answer' is the number that 'x' must be in order to make the statement true. If 'x' is anything different from -7, then the statement "x = -7" is not true. So the 'answer' must be -7 .

Must Be Proved Before They Can Be Accepted As True
A classic example of a statement that leads to a contradictory situation is the "liar paradox," expressed as "This statement is false." If the statement is true, then it must be false as it claims; however, if it is false, then it must be true, creating a logical contradiction. This paradox highlights the complexities and limitations of self-referential statements in logic and language.

One classic example of a paradox is the "liar paradox," which revolves around a statement that cannot consistently be true or false. An example would be the statement "This statement is false." If the statement is true, then it must be false, but if it is false, then it must be true, creating a paradoxical situation.
