Isolate everything, do the inverse until you have n on one side alone
OpenStudy (lena772):
If I knew how to do it, would I post it here?
OpenStudy (the_fizicx99):
Well, make an attempt. Distribute 7(c-4)
OpenStudy (lena772):
7c-28

-np>=7c-25
OpenStudy (the_fizicx99):
Add 3 to both sides
OpenStudy (the_fizicx99):
Divide by p both sides
OpenStudy (lena772):
-n>=(7c-25)/p
OpenStudy (the_fizicx99):
n can't be negative to you multiply it by -1. The sign changes

n<=-7c+25/-p
OpenStudy (lena772):
NOT AN ANSWER
OpenStudy (the_fizicx99):
P isn't negative. The entire equation is -_- H.S senior pro
OpenStudy (lena772):
you are misleading.
OpenStudy (the_fizicx99):

-sigh-
look at your options again..
OpenStudy (lena772):
is it b?
OpenStudy (lena772):
IS IT
OpenStudy (the_fizicx99):
Ya
-np - 3 ≥ 7(c-4)
-np - 3≥ 7c -28
+3 +3
-np ≥ 7c - 25
/p /p
-n ≥ 7c - 25 / p
/-1 /-1
n ≤ - ( 7c - 25 / p)
OpenStudy (lena772):
give me a medal i did gud work.

You freak. I don't mislead, you do. ( =.= )
