One other important thing -- and this one is common...

You only flip the sign when dividing by a negative number ... Not when you are dividing into a negative number!

When you do it:

 -5x < 10, ditch the -5 by dividing both sides by -5 AND flip the sign.  Alert!

When you don't do it:

4x is greater than or equal to -8, ditch the 4 by dividing both sides by 4. That's ok


YOUR TURN:

-10x < 30

5 - 7x is greater than or equal to 33
