Linear inequalities
The main application of linear inequalities is solving problems in which an unknown variable is dependent on a known variable. We solve linear inequalities by separating (sometimes described as "isolating") the unknown variable from the rest of the inequality. The unknown variable is usually, but not always, written as x.
An inequality of:
in which is the unknown variable, is a typical linear inequality with one unknown.
IMPORTANT: When you multiply or divide both sides of an inequality by a negative number, you must also flip the inequality sign.
REMEMBER: anything you do to one side of the inequality, you must also do to the other side of the inequality.
Linear inequalities contain one or more of the following symbols:
less than
less than or equal to
greater than
greater than or equal to
The solution to an inequality can be written in several ways:
Inequality notation:
Interval notation:
Set notation:
{X is a real number, }
Number line:
