Answer
No solution.
The graph is shown below.
Work Step by Step
The given inequality is
$\Rightarrow 8n+2\leq 8n-9$
Add $9$ to each side.
$\Rightarrow 8n+2+9\leq 8n-9+9$
Simplify.
$\Rightarrow 8n+11\leq 8n$
Subtract $8n$ from each side.
$\Rightarrow 8n+11-8n\leq 8n-8n$
Simplify.
$\Rightarrow 11\leq 0$
The inequality is false.
Hence, there is no solution.
