In this lesson, we will learn how to solve one-step linear inequalities by multiplication or division.

Students will be able to

deduce the multiplication property of inequalities, which is that when multiplying or dividing both sides of an inequality by the same number, the inequality stays balanced,
deduce the division property of inequalities, which is that both sides of an inequality can be multiplied or divided by a positive number without changing the inequality’s direction,
understand that if both sides of an inequality are multiplied or divided by a negative number, the direction will be changed,
know that solving one-step inequalities means finding the unknown value to make the statement true,
use rules to solve one-step inequalities.
