You aren't dividing or multiplying by a negative

To solve the inequality, you have to isolate $x$ by dividing by $9$ , which is a positive number.

If the inequality had been: $-9x$ > $-3/4$ , then $-9$ would have to be divided from each side and the sign would have to be flipped to <.

Why do you not change the inequality sign when solving 9x > - \frac{3}{4}9x > - \frac{3}{4}?
