-2x is greater than 1/9

answer: x is greater than -1/18

**Damon**, Tuesday, January 6, 2009 at 2:52pm- 2 x > 1/9

divide both sides by - 2 AND change direction of arrow

x < -1/18

when you multiply (divide) both sides of an inequality by a negative, you reverse the arrow

**Damon**, Tuesday, January 6, 2009 at 2:57pmThink about

-x > 1

that would be everything to the left of -1

Now do the algebra, multiply both sides by -1 and reverse arrow:

x < -1 sure enough
