## Introduction

**Definition:**An

**equation**is an algebraic statement that two expressions are equal. An equation consists of:

- a left-hand-side expression ,
- a right-hand-side expression, and
- an equal sign between them

## Examples and Explainations

Here are three examples:

- 5 + 3 = 8

- 5 + 3 = 9

*x*+ 4 = 10

**identity**. The second example is an equation that is never true; 5 plus 3 never equals 9. This is also known as a**contradiction**. The third example is known as a**conditional equation**. It is only**true**under the condition that the variable ,*x*, equals 6 since only 6 plus 4 equals 10. No other value of*x*makes the equation true. In this book we are primarily interested in conditional equations.Algebra Basics: Solving Basic Equations Part 1 - Math Antics
