$|x| \gt 2$
RECALL: The expression $|x-a|$ represents the distance of a real number $x$ from $a$. Thus, the expression $|x-0|$, which is equivalent to $|x|$, represents the distance of the real number $x$ from 0. Therefore, the expression $|x|>2$ means: "the distance of a real number $x$ from 0 is more than 2 units"
