Mastering Two Step Inequalities

What is the key difference between solving two-step equations and two-step inequalities?

• The use of inequality symbols

• The presence of variables

• The need for addition

• The use of multiplication

What must you do to the inequality symbol when you multiply or divide by a negative number?

• Leave it unchanged

• Flip it

• Remove it

• Double it
