5x%2B9-7x%3E=21 Start with the given inequality.


9-2x%3E=21 Combine like terms on the left side.


-2x%3E=21-9 Subtract 9 from both sides.


-2x%3E=12 Combine like terms on the right side.


x%3C=%2812%29%2F%28-2%29 Divide both sides by -2 to isolate x. note: Remember, the inequality sign flips when we divide both sides by a negative number.


x%3C=-6 Reduce.
