It also provides you a feature to save the solution in PDF format.

It is available in both free and paid versions. Its free version lets you solve only the algebraic equations. For more advanced features, like **Simplification, Trigonometry, Intermediate Graphs, Complex Numbers, Inequalities, Differentiation**, etc., you have to purchase its full version.

## Two Equations - Two Unknowns

**Two Equations – Two Unknowns** is a free system for linear equations calculator for Windows. It is a linear equation calculator which lets you solve for x and for y. It is suitable for solving a linear equation with two variables.

The two linear equations displayed on the interface follows the format: ax + by = c and dx + ey = f. Here, *a, b, c, d, e*, and *f* are the constant terms of linear equations with two variables. To solve for x and y, you have to enter the value of these constants in the provided space. When you are done, click *Solve* button and you will get your solution immediately.

There are many methods to solve linear equations with two variables. This linear equation solver follows the *Cramer’s Rule* to solve the linear equations.

The best part of this free calculator is that it plots an X vs Y graph with two different colors for every entered problem.

## Ro3n

**Ro3n** is another free system of linear equation solver with 3 unknowns. By default, it is set to solve linear equations with three variables. You can also use it to solve linear equations with 2 variables.

Empty boxes are provided in place of coefficients of variables. You have to put values of coefficients in these empty boxes in order to solve a linear equation. After entering values of all coefficients, click *Solve* button and get an immediate solution.

It uses matrix method to solve the system of linear equations. Along with the separate values of x, y, and z, it also displays main determinant, 1st determinant, 2nd determinant, and 3rd determinant of the matrix thus obtained.

It displays the determinant values only for the linear equations with three variables. For the system of linear equations with two variables, it only displays the final result.

### Additional features of this free linear equation calculator:

- It is intended to solve both linear and quadratic equations.
- You can export the result in HTML as well as in TXT file formats.
- It supports more than 5 languages, which include:
**English, Slovak,****German****, French**, etc. - It comes with 5 attractive skins:
**Windows Style, Windows XP Style, Motif Style, CDE Style,**and**Plastique Style**.

## Calculatormatik

**Calculatormatik** is another system of linear equation calculator.

It is intended to solve linear equations with three variables. You just have to enter the values of coefficients of x, y, and z in order to find the values of all of these variables.

Calculatormatik is an advanced calculator in this list. It comes with lots of built-in calculators which you need in your daily studies. Other than calculators, you will also find several unit converters in it. Below, I have listed the names of some of these calculators and unit-converters:

**Calculators**: LCM Calculator, Quadratic Equation Solver, Birthday Calculator, BMI Calculator, Prime Factor Calculator, Compound Interest Calculator, Simple Interest Calculator, Profit Calculator, Volume Calculator, Water Consumption Calculator, etc.**Unit Converters**: Byte Converter, Density Converter, Electric Capacitor Converter, Energy/Power Converter, Flow Converter, Hex to ASCII Converter, Temperature Converter, etc.

## Linear Equation System Solver

**Linear Equation System Solver** is another free system of linear equation calculator. It lets you compute the linear equations with three variables. It is a JAVA based program, which needs JAVA to run on a PC.

You need not install this software on your PC, as it is a portable software. Just click its executable file and hit *Enter* button.

Three empty spaces are provided on its interface to enter the three linear equations separately. You have to enter the complete linear equations in each of these empty spaces. When you are done, press *Solve* button and get an immediate solution.

## Math Hub Basic

**Math Hub Basic** is a free Windows 10 app to solve linear equations with one variable. Hence, you can only solve for X using this freeware.

It shows the format of linear equation with one variable: AX + B = C. Here A, B, and C are constants. You have to enter the values of these constant terms and the app solves the linear equation for X. It is actually a step by step math problem solver. Hence, you can learn the proper way to solve the system of linear equations with one variable.

Other than Linear equations calculator, it features three more calculators, which will be beneficial for you. These three calculators are Quadratic Equation Calculator, Biquadratic Equation Calculator, and Logarithmic Calculator. All these three calculators also give step by step solution of the entered math problem.

## A-Level Physics Calculator

**A-Level Physics Calculator** is a very good physics calculator, which is intended to do some algebraic calculations.

This Windows 10 app lets you solve a system of linear equations with two variables. You just have to enter the values of coefficients in the empty boxes and it displays the result automatically. It solves the linear equation for both x and y, i.e., you will get the values of both the variables of linear equations simultaneously.

Apart from linear equations calculator, it features some other calculators, which include: Quadratic Equation Calculator, SUVAT Motion Calculator, Projectile Motion Calculator, etc.

## Mathematic Tools

**Mathematic Tools** is another free Linear Equation Calculator app for Windows 10. This is a very simple app, which lets you calculate only the linear equation with one variable. In other words, you can only solve for x using this software.

In order to get the solution of a linear equation with one variable, you just have to enter the values of its coefficients.

### Advantages of this free linear equation calculator:

- It lets you calculate the roots of a quadratic equation.
- It also contains some Mathematical Formulae, like
**Trigonometric ratios, Logarithms, Exponents, and Radicals, Geometric formulae**, etc. - It has a built-in calculator, which has some advanced features, like
**Trigonometrical Calculations, Radian to Degree Conversions and vice versa, Log, Factorial, nth Power of a number**, etc.

The only disadvantage that I found in this calculator is that it is not designed to solve linear equations with more than one variable. Moreover, in the expression ax + b = c, constant c is fixed to zero, which further restricts its usage for solving linear equation.
