This is a compound inequality. You can google that, for more information. :cool:

It should be "less than" and "to".

This can be broken into two inequalities:
$\displaystyle -2 \le 3x+ 10$ and $\displaystyle 3x+ 10\le 31$.
Can you solve each of those?

The solution set for this "compound inequality" is the set of values of x that satisfy both.
