B. Because the absolute value of a number is the distance of that number from 0.
Answer:

Step-by-step explanation:
Given: 
To solve for
, we have to isolate it on one side of the equal sign. Let's start by getting rid of that coefficient of
from
. To do that, divide by 

To isolate
all we need to do is put it on one side of the equal sign. Let's subtract
from both sides to get
all by itself.

We aren't done yet, we solved for
not
. All we need to do is divide everything by
to cancel out the negative sign on
. What that basically does is change ALL the signs.
