Equations and Expressions


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.
