p/(-2)<-5
Multiply both sides by -2; keep in mind that when you multiply
or divide an inequality by a negative the inequality is reversed.
------
The left side becomes p
The right side becomes 10
The < becomes >
You get:
p>10

Clear of fractions by multiplying both sides by -5
BUT, you must remember that the rules are:

1. When multiplying or dividing an inequality by a
   POSITIVE number, you DO NOT reverse the direction
   of the inequality.

2. When multiplying or dividing an inequality by a
   NEGATIVE number, you MUST reverse the direction
   of the inequality.

This is a case of multiplying an inequality by a
NEGATIVE number, so we must change the < to a >



     

If you are asked for interval notation, the
answer is:

    (10,¥)
