How to Put Mathematical Systems Into Wolfram Alpha

You can solve systems of equations in Wolfram Alpha.

Wolfram Alpha is free mathematical software. You can use Wolfram Alpha to solve mathematical problems including arithmetic, trigonometric and algebraic problems, as well as integrals and derivatives used in calculus. It can also be used to solve systems of equations, meaning a series of equations used to solve for more than one variable.

Instructions

1. Open your Web browser and go to the Wolfram Alpha homepage. Type "equations" into the dialogue box in the center of the page. Scroll down to the bar that says "systems of equations," which should have a pretyped example to show you how to handle systems.

2. Use the "Systems of Equations" dialogue box on the "Equations" page to solve systems of equations with two variables. This dialogue box has two fields. Type the first equation into the first field and the second equation into the second.

3. Return to the Wolfram Alpha homepage to solve systems of equations with more than two variables. Write each equation into the dialogue box, separating the equations with commas. For example, enter a three-variable system into the dialogue box like this: "x+2y+z = 8, 2x - y + z = 3, 5x+5y+5z = 30." Press "Enter" to see a solution to your system.
