92 >/= -4 p
divide both sides by -4
Rule:
When you multiply or divide both sides of an inequality by a NEGATIVE quantity, you CHANGE the DIRECTION of the arrow
So:
-23 </= p
divide both sides by -4

Damon,
Thanks for the help. Let me see if I get it now. So,
-2x < -4
divide both sides by -2
answer is x > 2
I had x < 2, but I reverse the sign since I divided by a -2 on both sides, correct?
