That is absolute value.


|x|\text{ = +x or -x}
\begin{gathered} |-8a\text > 11 \\ (-8a\text{ - 3) > 11 or -(-8a - 3) > 11} \\ (-8a\text{ - 3) > 11} \\ -8a\text{ > 11 + 3} \\ -8a\text{ > 14} \\ a\text{ < }(-14)/(8) \\ a\text{ < }(-7)/(2) \end{gathered}

or


\begin{gathered} -(-8a\text{ - 3) > 11} \\ 8a\text{ + 3 > 11} \\ 8a\text{ > 11 - 3} \\ 8a\text{ > 8} \\ a\text{ > 8/8} \\ a\text{ > 1} \end{gathered}

Therefore,

1 < a <-7/2
