Calculator for three linear equations

A Calculator for Three Linear Equations is a tool that solves a system of three linear equations with three variables. It finds the values of the variables that satisfy all three equations simultaneously.

Why Use It?

• Manually solving three equations can be time-consuming and error-prone.
• A calculator quickly computes the solution using mathematical methods like substitution, elimination, or matrix (Gaussian elimination, Cramer's rule, inverse matrix method).
• Useful in engineering, physics, finance, and various applied sciences.

How Does It Work?

1. You input three linear equations in the form:
   ax+by+cz=d
   ex+fy+gz=h
   ix+jy+kz=l
2. The calculator uses algebraic methods to find the unique solution for x, y, and z (if one exists).
3. It displays the values of x, y, and z, or indicates if there's no solution or infinite solutions (if the equations are dependent).

When to Use It?

• When solving physics problems involving forces or motion.
• In economics for solving equilibrium equations.
• In computer graphics and 3D modeling.
• For solving circuit equations in electrical engineering.
