Question 480247: For what values of a is the equation /a/=6 true
Answer by tinbar(133)   (Show Source):
You can put this solution on YOUR website! I'm going to assume /a/ is really supposed to be |a|, which refers to the absolute value of a. So what numbers have absolute value (magnitude) or 6?
+6 is an obvious answer. However, -6 is also an answer since it's 'magnitude' is 6 units.
In general, |a| = +a and -a
