Answer:
{x | x > -4}
Step-by-step explanation:
The direction of the < or > sign only changes when numbers are multiplied or divided by negatives.
Because to simplify 9x > -36 you only need to divide by 9, the sign stays the same and the numbers are simply divided:
x > -4
So the solutuon set would be:
<h3>{x | x > -4}</h3><h2>Hope this helps!</h2>
