Solving Equations by Multiplying or dividing • Objectives: • Write and solve one step equations with one variable by using multiplication and division

Solving Equations • Yesterday we talk about solving equations and how we can add or subtract to both sides so state the same. Today we are going to use the same concept but we are going to multiply or divide. We are going to use two properties : • Division Property of equality : we can divide both sides by a non zero number and the equation remain the same. • Multiplication Property of equality: we can multiply both sides by a non zero number and the equation remain the same
