## Introduction

In this lesson, we will learn the difference between Equations ans Expressions. Before we begin with examples for each, let's go over the definitions of these terms:Key Terms

- Expression uses variables, numbers, and operations to express a value in algebra
- Equation shows that two Expressions are equal using the "=" sign

## Equations vs. Expressions

Equations and Expressions-both are used algebra.The difference between Equations and Expressions is that Equations show equalities and inequalities while Expressions do NOT have a value for the variables. Therefore, Expressions can NOT be solved, only simplified.
