Increased by 12 means plus 12. The word "is" in equations is an equal sign. So far, you have 2n+12. On the other side of the equal sign, you have 31 less than 3 times a number.

Solve the compound inequality 9 + 3n >= 6 or 5n < 25.

babymother [125]

$9+3n \geq 6 \ \lor \ 5n\ \textless \ 25 \\
3n \geq 6-9 \ \lor \ n \ \textless \ \frac{25}{5} \\
3n \geq -3 \ \lor \ n \ \textless \ 5 \\
n \geq \frac{-3}{3} \\
n \geq -1 \\ \\
\boxed{n \geq -1 \hbox{ or } n\ \textless \ 5} \\ \\
\hbox{answer C}$
