Solve for |a|.
|a|=8
Now, a can be either negative or positive. If it is positive, then we can take off the absolute value signs. If it is negative, then we must change a to -a, then take off the absolute value signs.
Positive:
a=8
Negative:
-a=8
a= -8
Your 2 answers are a=8 and -8.
I hope that this helps.
