[AI-generated answer — Bot GPT 3.5]

The symbol ≠ (not equal to) can be used to represent an inequality with a solution set containing all real numbers but one. One example is:

$x ≠ a$
where $a$ is any chosen real number. In this case, the solution set is all real numbers except for the specific value $a$.
