## Introduction

In tutorial 6.1, we discussed algebraic expressions and their components. Do you remember what are they? What elements does an algebraic expression contain?

What do you obtain when substituting the values of variables in algebraic expressions with numbers?

Do you know what an equation is? What are the components of an equation?

In this tutorial, we will deal with the concept of equation, its components, and provide example of methods that show you how to work with them. To illustrate this concept, we will use the first - order equation, as the simplest type of equation.
