While this is a very intuitive way to do it, but suppose we have a number x < 0
In other words, we have a negative number, say -5
What is |-5| ?

anonymous · Answer

when x<0, |x| is equivalent to (-x)
when x>0, |x| is equivalent to (x)

anonymous · Answer

so is it always, sometimes, or never true?

anonymous · Answer

it is never true.. if  -5<0 the |-5|=-(-5)=5 & not simply -5 
however if x>0 then it is always true
