test them out
OpenStudy (anonymous):
I got for my answers
|-13| = -13
and
|13/3| = -13/3
So would the answer be C or No solution?
OpenStudy (amistre64):
does |-a| = -a ?
OpenStudy (anonymous):
Nope
OpenStudy (anonymous):
Isn' abs value supposed to be equal to a positive? Im rusty lol

absolute values are never negative ... so x < 5 is not going to produce any valid results.
so, either a solution exists; or none exists ... which do you think it should be and why?
OpenStudy (anonymous):
I'm assuming none since |-a| = a and \[a \neq a\]
OpenStudy (anonymous):
a =/ -a **
OpenStudy (amistre64):
none exist ...
either:
2x+3 = x-5 , such that x>5
x=-8
or
-(2x+3) = x-5, such that x > 5
2 = 3x
x=2/3
neither 'solution' is valid
