Answer 2

$21k-3n+9p\ \textgreater \ 3p+12 \\21k-3n+9p+(-21k)\ \textgreater \ 3p+12+(-21k) \\-3n+9p\ \textgreater \ -21k+3p+12 \\-3n+9p+(-9p)\ \textgreater \ -21k+3p+12+(-9p) \\-3n\ \textgreater \ -21k-6p+12 \\\frac{-3n}{-3}\ \textgreater \ \frac{-21k-6p+12}{-3} \\n\ \textless \ 7k+2p-4$

Your answer is $n\ \textless \ 7k+2p-4$.
