## What Are Simultaneous Equation?

Simultaneous equations are a set of several equations with several unknowns.

There are a set of values of these unknowns which solve all the equations at the same time.

Here are set of simultaneous equations. They are both linear equations:

Both equations are solved by the same values of **x** and **y**. **x = 2** and **y = 1** solve both equations.

### Dictionary Definition

The Merriam-Webster dictionary defines simultaneous equation as "satisfied by the same values of the variables."

## Where Does the Word Simultaneous Come From?

Simultaneous equations are so called because the solution solves all the equations at the same time, or simultaneously.

## Simultaneous Equations

Simultaneous equations are two or more equations that are solved by the same values of the variables.

The most common types of simultaneous equations are two linear equations.

In this mini-curriculum, you will learn about simultaneous equations.

## Solving Simultaneous Equations

Solving simultaneous equations means finding the values of the variables ( **x** and **y**) that make both equations equal.

There are different ways to solve simultaneous equations.

In this mini-curriculum, you will learn how to solve simultaneous equations.
