Subtract 5 from both sides of the inequality.
Then divide both sides by -2.
**Remember to turn the inequality around. It will become greater than or equal to.
OpenStudy (lisa2345):

OpenStudy (lisa2345):
At first I thought it was A

Okay, so the answer cannot be A or B.
OpenStudy (ajspeller):
Only switch the symbol when you divide or multiply by a negative number.
OpenStudy (lisa2345):
is the answer C?
OpenStudy (ajspeller):
No, because the inequality symbol has to be turned around.
OpenStudy (lisa2345):
Oh yeah because I didn't divide or multiply by a negative number so it's D? @ajspeller

You did divide by a negative number. -2
-18/-2 = 9
OpenStudy (lisa2345):
No I meant the other question I posted

The answer to the 2nd question is not D. You have to add 8 to both sides.
