A **system of equations is a set of two or more algebraic equalities with several unknowns**, these equalities are related to each other since the value of the unknowns satisfy all the equations. Example:

5x-3y+4z=-1 |

-3x-6y=14z |

4x+8z=12 |

Systems of equations can be classified according to different criteria.

If we take into account the degree of the equations, the systems of equations can be classified into:

- Linear system: if all the equations are linear.
- Nonlinear system: if not all equations are linear.

On the other hand, systems of equations can also be classified according to the number of equations or unknowns:

- Systems of two equations or Systems of two unknowns.
- Systems of three equations or Systems of three unknowns.
- etc. . . . .

Depending on the type of solutions, a system of equations can be classified as:

- Specified supported system. It is a system that has only one solution.
- Undetermined compatible system. An indeterminate compatible system has infinitely many solutions.
- Incompatible system. An incompatible system has no solution.

The most used algebraic methods to solve systems of equations are the following:

• Substitution method

• Elimination method

The System of equations calculator uses the substitution and elimination methods.

It is important to keep in mind that the solution of a system of equations must be the same regardless of the method used to solve it. Each of the previously presented methods will be explained below and to make the explanation easier to understand, we will show how to solve the following system of equations using the three methods:

5x-32y=-1 |

-3x-6y=14 |

It consists of isolating an unknown variable in one of the equations and substituting it in the other. Now we present how to solve by substitution the system shown above:

In this method, the two equations are prepared so that one of the unknown variables has the same coefficient in both but with different signs. Adding the equations we get an equation with a single unknown variable.
