<em>Comment on solving inequalities</em>
An inequality is solved in virtually the same way that an equation is solved: <em>undo what is done to the variable</em>. The only difference is that when you perform an operation that reverses the ordering, you need to reverse the ordering symbol.
Multiplying or dividing by a negative number will reverse the ordering. Consider, for example, ...
2 > 1
Multiplying both sides by -1, we get ...
-2 < -1 . . . . . the > sign needs to be reversed to a < sign to keep the inequality true
