Solving linear equations using multiplication and division
In the previous lessons, we have learned what a linear relationship is and its graphs and tables. In this lesson here, we will then learn how to solve one-step linear equations by multiplication and division.
Basic Concepts: Evaluating algebraic expressions, Solving one - step equations: x+a=b, Model and solve one-step linear equations: ax=b, ax=b
Related Concepts: Express linear inequalities graphically and algebraically, Introduction to linear equations, Introduction to nonlinear equations
