Solving Two-Step Inequalities

What is an inequality in mathematics?

• A mathematical sentence that compares quantities.

• A mathematical sentence that involves addition and subtraction.

• A mathematical sentence that shows equality.

• A mathematical sentence that only has one solution.

Which of the following is NOT an inequality symbol?

• Less than or equal to

• Equal to

• Greater than

• Less than

When graphing inequalities, what must you remember to do when multiplying or dividing by a negative number?

• Keep the inequality sign the same.

• Subtract a negative sign from the result.

• Flip the inequality sign.

• Add a negative sign to the result.

Why do we flip the inequality sign when multiplying or dividing by a negative number?

• To simplify the equation.

• To make the inequality false.

• To keep the inequality true.

• To change the variable.

What is the first step in solving a two-step inequality?

• Multiply both sides by a number.

• Divide both sides by a number.

• Subtract a number from both sides.

• Add a number to both sides.
