$x$ $x$ > $- \frac{7}{2}$ $-7/2$

Explanation:

We want to get $x$ $x$ alone in this inequality. To do this, we divide each side by -2 (but remember, when you divide or multiply by a negative number in an inequality, you switch the sign)

$- 2 x$ $-2x$ < $7$ $7$ (divide each side by -2)

Divide each side by $- 2$ $-2$ and switch the inequality sign:

$x$ $x$ > $- \frac{7}{2}$ $-7/2$
