$z > 21$

#### Explanation:

Inequalities may be solved the same as equations except in the case when you need to multiply or divide the inequality by a negative number - in this case, the sign of the inequality changes around.

$\therefore - 273 > - 13 z$ implies that $\frac{- 273}{- 13} < z$

$\therefore z > 21$.
