Lesson Summary:

In this lesson, we learn about the multiplication property of equality and how to clear denominators when fractions are involved in solving linear equations. We see how we can multiply or divide the same non-zero number to both sides of the equation so that we can undo what was multiplied by the variable and get the same solutions. Additionally, we learn how to simplify complex fractions and how to get rid of fractions by finding the least common denominator and multiplying both sides of the equation, making solving equations with fractions easier.

Lesson Description:

Part 5 of Solving Linear Equations in one variable. Covers solving linear equations using the multiplication property of equality and how to clear denominators when fractions are involved.
