Question

I just need help with the first step

Answer 1

\[1-8\left| 5+a \right|=-31\]

Answer 2

hints:
1. subtract a 1 on both sides.
2. then, divided by 8 on both sides.
3. break it down into 2 parts \[5+a = +?\] and \[5+a = -?\] ...do you understand why it is broken down into 2 parts?

Answer 3
