IT & INTERNET - [Equation Solver]

Equation Solver

This Equation solver allows you to solve a system of linear equations. I have written this solver in Java, because I have to deal a lot with this kind of equations. This program obviously speeds up the calculation of these equations.

Usage of this solver

You need to enter equations in the textbox. For composing equations, you are currently limited to 26 variables (characters A to Z) and the use of integers only.

Once all equations are given, you need to press the "Solve!" button. The applet will then calculate and offer you the solution of the system. Be aware: there is no guarantee that the solution is correctly. An example usage for this program:

Together, An and Jan are 43 years old. An is 20 year older than Jan. How old are An and Jan?

Compose equation 1: A+J=43
Compose equation 2: A=J+20
Press the button 'Los Op!'
Results: A=31.5 and J=11.5.

Conclusion: An is 31.5 years old, while Jan is 11.5 years old.

Examples of equations

A+B=20
10A-B+W=40C
10A+B=0
...

Limitations

If you use x variables, you need to have x equations. Therefore, there is a limit of 26 equations/variables.
A variable is represented by a single character, between A and Z
Only integers can be calculated
