Facts about Linear Equations inform us with the algebraic equation. It may have a single variable. It should be written in the form of ax + b = 0 if it has one variable. It is considered as the simple equation. In this case, a ≠ 0.  The constants refer to a and b. The parameters, numbers, and non-linear functions of parameters may serve as the constants. Here are other interesting facts about linear equations:

## Facts about Linear Equations 1: the variables

The simple equation may only have a single variable.  However, it may have more variables. The ax + by + cz + d = 0 is an example of linear equation which consists of three variables of x, y, and z. The non-zero is seen on the a, b, and c. The constants are seen on a, b, c, and d. linear equation Pic

### Facts about Linear Equations 2: the importance of linear equations

Most fields of mathematics and applied mathematics often used linear equations.
