5. Working with inequalities is similar to working with equations. A solution to a one-variable inequality is a value for the variable that makes the inequality true. The set of all solutions to an inequality is a set of numbers that
all make the inequality true. The solution to a one-variable inequality is usually graphed on a number line.
Most of the properties of equality can also be used to solve inequalities. The only exception is that when you
multiply or divide both sides of an inequality by a negative number, you must reverse the direction of the
inequality sign to produce an equivalent inequality.
