We see a lot of abs values in GMAT Practice sets.
Can you draw an example of |x-1| > |x|

I have taken a randon value. This could help to generalise

First of all note that such an inequality will imply a range of values of x where it is true.

Consider the graphs of |x| & |x-1| :

The shaded region is where |x-1| is greater than |x|

So this inequality represents x<0.5

Great post.
My suggestion will be always convert inequalities to the normal view:
y < 2x+ 38393
and then to apply memorized rules applied for that type of expression. Otherwise, there is too much stuff to remember:)
