Understanding Two-Step Inequalities

What is the key difference when solving inequalities compared to equations?

• There is no difference in the method.

• You reverse the inequality symbol when adding or subtracting.

• You must use a different set of numbers.

• You reverse the inequality symbol when multiplying or dividing by a negative number.
