A linear equation solver is a tool that can be used to find the solutions to systems of linear equations. Systems of linear equations are a common type of mathematical problem that arise in many different fields, such as engineering, physics, and economics.

Linear equation solvers can be used to solve systems of linear equations of any size and complexity. However, as the size and complexity of the system increases, the time required to solve the system using a linear equation solver also increases.

There are many different types of linear equation solvers available. Some of the most common types include:

- Gaussian elimination
- LU decomposition
- QR decomposition
- Jacobi iteration
- Gauss-Seidel iteration

**How to Use a Linear Equation Solver**

To use a linear equation solver, you first need to input the system of linear equations that you want to solve. The linear equation solver will then use one of the methods listed above to find the solutions to the system.

Once the linear equation solver has found the solutions to the system, it will typically output the solutions in a format that is easy to read and understand. For example, the linear equation solver may output the solutions in a table or in a graph.
