Hi there!
Let's solve this equation step by step!
![|x| - 7 = 6](https://tex.z-dn.net/?f=%20%7Cx%7C%20%20-%207%20%3D%206)
First add 7 to both sides.
![|x| = 13](https://tex.z-dn.net/?f=%20%7Cx%7C%20%20%3D%2013)
Next we need to take a look at the meaning of the stripes between our variable. Those stripes mean we are dealing with an absolute value function. The absolute value stripes make everything between the stripes positive; also when we plug in a number. In this particular question we can plug in both -13 and 13 at the position of n, because when -13 is made positive, it fulfils the equation.
Hence,
![x= 13](https://tex.z-dn.net/?f=x%3D%2013)
or
![x = - 13](https://tex.z-dn.net/?f=x%20%3D%20-%2013)
~ Hope this helps you!

A division in half can yield different results. Take a square for instance, you can divide it in half by cutting along the diagonal, or cutting parallel to the borders.
However, dividing by half yields a unique result, like in
![\frac{4}2=2](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D2%3D2)
.
