**Nick**, Wednesday, July 16, 2008 at 7:37pmYou forgot to reverse the greater than sign when dividing by a negative number.

Take this example: -2*x < 10.

Pick a number for x that satisfies the equation--: For instance, if x=3, then

-2*(3) < 10 ----> -6 < 10 is true.

Solved without flipping the less than sign makes your equation (with x plugged in) gives you 3 < 10/(-2) ---> 3 < -5 WRONG.

Whenever you multiply or divide both sides of the equation by a negative number, you have to reverse the inequality.

If in doubt, plug in a number for x that works in the first place, and see if it still works at the end.
