Our online service allows us to solve systems of linear algebraic equations in various ways:

- by Cramer's method (Cramer's rule)
- inverse matrix method
- by the Gauss-Montante method (the Bareys algorithm)
- by the method of Gauss (method of sequential elimination of variables)
- by the Gauss-Jordan method (the method of completely eliminating unknowns)

In this case, the service provides a sequence of solutions, not just the answer.

In addition, you can check the system of equations for compatibility.

- Use the
**+**and**-**signs to specify the required number of variables in the equation. If your equation does not include any unknowns, then just leave the fields blank (blank). - In cells, specify the coefficients (values) for unknowns. If the initial data indicates the value x
_{1}, x_{2}and so on, in the cell before the specified unknowns, specify the value 1. - Values for unknowns can be:
- whole numbers:
`7`

,`-3`

,`0`

- decimal (finite and periodic) fractions:
`7/8`

,`6.13`

,`-1.3(56)`

,`1.2e-4`

- arithmetic expressions:
`1/2+3*(6-4)`

,`(6-y)/x^3`

,`2^0.5`

- whole numbers:
- Then click on the button with the name of the required mathematical operation.
- The values in the solution results can be dragged with the mouse to the source data field.
