Problems 3-17
See Example 1.
Make sure the variable is on the left in order to easily graph the solution. The
symbol is "<" then the solution is to the left; if it is ">", then the solution is to
the right. The endpoints are not included for these symbols. If the inequality
symbol is
less than or equal to or greater than or equal to, then include
the endpoint.
Remember, the inequality symbol reversed if you multiply or divide by a negative
number, or if you reverse the right and left sides.
