​Solving Inequalities

​In the last lesson we learned that you can solve an inequality the same way as you would solve an equation, with one difference: when you multiply or divide by a negative number, the inequality will reverse.

​

The next three questions are about solving inequalities.

​

• Simplify both sides of the expression.

• ​Move variable terms to one side of the equation using the properties of equality.

• ​Solve using the properties of equality.

​In the first lesson we learned that you plot an inequality on a number line.

​

The next three questions are about plotting the solutions of inequalities.

​

• > or < open circle because they do not include the value.

• ≥ or ≤ closed circle because they do include the value.

Writing Inequalities

​In the first lesson of this module we learned how to pick out key words in order to write an inequality based on word problems.
