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, Model and solve one-step linear equations: $ax = b$, $\frac{x}{a} = b$,

Related concepts: Express linear inequalities graphically and algebraically, Introduction to linear equations, Introduction to nonlinear equations,
