\({|6 - x | = 2}\), where \({x = 4, 8}\)

I understand where the 4 came from, but how did they come up with 8?

l 6 - x  l  = 2

 

We actually have two equations here

 

6 - x  = 2               and              6 - x  =  -2

 

                           subtract 6 from both sides

 

-x  = - 4                                      -x   =  -8

 

                          multiply through by  -1

 

x  = 4                                           x  = 8
