Do the equations
$|x|<a$ and $x<|a|$ have the same solutions , i.e
$-a<x<a$
In general , do the two equations mean the same thing , that the absolute value of $x$ is less that the distance of $a$ from the origin , on either side of the origin ?

If $a=-1$, then$$x<|a|\iff-1<x<1,$$whereas there is no $x$ such that $|x|<a$.
