the problem is 92 is greater than or equal to negative 4p.
why is the answer p is greater than or equal to negative 23?
I am confused! why is it not p is less than or equal to negative 23?

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

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?
