Multiply both sides of the inequality by -1%2F2. When you do, remember that when you multiply or divide both sides of an inequality by a NEGATIVE number, you must REVERSE the inequality.

%28-2x%29%2A%28-1%2F2%29+%3E+%281%2F9%29%2A%28-1%2F2%29+
x+%3C-1%2F18

Solution set is {x|x<-1/18}.

Yes, you are correct!
