\(15\ \textgreater \ -3x \\ \\ - \frac{15}{3} \ \textless \ x \\ \\ -5 \ \textless \ x \\ \\ x \ \textgreater \ -5 \\ \\\)
The final result is: x > -5.
-------
\(\frac{2}{5} x \ \textgreater \ -2 \\ \\ \frac{2x}{5} \ \textgreater \ -2 \\ \\ 2x \ \textgreater \ -2 \times 5 \\ \\ 2x \ \textgreater \ -10 \\ \\ x \ \textgreater \ - \frac{10}{2} \\ \\ x \ \textgreater \ -5 \\ \\\)
The final result is: x > -5.
