Oh thank you so much
You are very welcome.
When you multiply or divide an inequation by a negative number the inequality sign must be reversed.
e.g.
-5 < 4 is a true statement, but
when I multiply be -1, the statement
5 < -4 would be false
but 5 > -4 makes it true, so .....
-5p > -55
divide both sides by -5
p < 11
e.g.
-5 < 4 is a true statement, but
when I multiply be -1, the statement
5 < -4 would be false
but 5 > -4 makes it true, so .....
-5p > -55
divide both sides by -5
p < 11
Reiny is right. I forgot to change the sign.
Thank you Reiny and Ms. Sue I got it now and can do other similar problems myself ((:
you are both welcome
