**CL**, Monday, May 10, 2010 at 11:23pm-5x > 0

-5x/-5 > 0/-5

x < 0 since we are dividing by a negative, the inequality changes

so, no the answer is not the same

9x > 81

x > 81/9

x > 9

**Do**, Monday, May 10, 2010 at 11:25pmfirst one no:

when dividing by a negative you need to flip the inequality sign

-5x > 0 = x < 0

x<0 doesn't equal x>0

the second

x> 81/9

x> 9
