Solving Inequalities

By: Nikki P.

The Problem:

-4+ r <12

Work:

What I did was, I added 4 on both sides of the equation. I added 4 on both sides because we have do the opposite. So now the work looks like this

-4 + r <12

+4 +4

r < 16

Now you have r is less than 16. So now we have to graph it.
