**Damon**, Monday, June 16, 2008 at 8:40pm2. x + 3 > 2x + 1 and -4x < -8

note if you divide by negative number, change arrow direction

2 > x and x > 2 can not be both

**Damon**, Monday, June 16, 2008 at 8:57pm4. -3x > -6 or x - 5 < 2

x < 2

or x < 7

everything left of seven satisfies the second, everything left of 2 satisfies both. In other words x<2 is a subset of x <7

**Damon**, Monday, June 16, 2008 at 9:02pm5. x - 2 > 2x + 1 or 10 > -2x + 2
