Solving Equations

Solving equations is central to mathematics—and economics is no exception. This chapter introduces types of equations commonly found in economic models. While many students are familiar with equations involving a single variable (like $x$), working with multiple variables—each with different names—can feel challenging at first. However, this skill is essential in Econometrics and Operations Research and in Econometrics and Data Science. Being comfortable with multi-variable algebraic expressions will help you better understand and build economic models. With practice, you'll gain the confidence to handle these equations with ease.

This section is based on Chapter 3 of Essential Mathematics for Economic Analysis.
