-2x%3E1%2F9 Start with the given inequality.


9%28-2x%29%3Ecross%289%29%281%2Fcross%289%29%29 Multiply both sides by 9.


-18x%3E1 Multiply.


x%3C%281%29%2F%28-18%29 Divide both sides by -18 to isolate x. note: Remember, the inequality sign flips when we divide both sides by a negative number.


x%3C-1%2F18 Reduce.

Answer:

So the answer is x%3C-1%2F18


Which approximates to x%3C-0.056


So the answer in set-builder notation is
