<em>Comment on solving inequalities</em>
In general, you solve these the same way you would an equation. The difference comes when you use an operation that changes ordering. <em>Multiplying or dividing by a negative number</em> does that, for instance.
Consider ...
2 > 1.
Multiply both sides by -1, and it is true only if you reverse the comparison:
-2 < -1
(There are other operations that change ordering, but this is the one you will likely run across most often.)
