Solve Inequalities Using Addition and Subtraction - Example 3

In mathematics, an inequality is a statement that one number is greater than or less than another number. The notation a ? b means that a is less than or equal b. The notation a ? b means that a is greater than or equal to b. If the two numbers have the same sign, the relationship is positive (or less-than) and if they have different signs, the relationship is negative (or greater-than).
