Equations and Expressions

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.
