$x > - 5$

#### Explanation:

When solving an inequality you treat it in the same way as an equation, except if you divide or multiply by a negative number, the inequality sign changes around.

$- 3 x < 15 \text{ } \leftarrow$ to isolate $x$ divide by $- 3$

$\frac{- 3 x}{- 3} > \frac{15}{- 3} \text{ } \leftarrow$ note the sign change

$x > - 5$
