Here's what I did:

Combine like terms: -3|6n-8| = -107
Add 3 to both sdies: |6n-8| = -104

What am I doing wrong here?

5 - 8|6n-8| = -107
5                 = -107 + 8|6n-8|              (add 8|6n-8| to both sides)
5 + 107       = 8|6n-8|                          (add 107 to both sides)
112              = 8|6n-8|

can you work out the rest?

anonymous · Answer

Yeah, but where did she get 

6n-8 = 14

asnaseer · Answer

what would you get if you divided both sides by 8 (on my last equation up there)
