System of Equations Calculator

Category: Algebra II

Enter up to three equations and variables to calculate a system of equations step-by-step.

System of Equations Calculator

The System of Equations Calculator allows you to solve a system of linear equations involving two or three variables. Whether you are solving for simple systems like 2x + y = 5 or more complex systems with three variables, this tool provides accurate solutions with step-by-step explanations.

What is a System of Equations?

A system of equations is a set of two or more equations that involve the same variables. The goal is to find values for these variables that satisfy all the equations simultaneously.

For example, consider the following system of two equations:

  • 2x + y = 5
  • x - y = 1

The solution is x = 2 and y = 1 because these values satisfy both equations.

Frequently Asked Questions (FAQ)

What types of systems can this calculator solve?

This calculator can solve linear systems involving up to three variables. Examples include:

  • Two-variable systems like 2x + y = 5 and x - y = 1.
  • Three-variable systems like 2x + y - z = 1.

How does the calculator solve the equations?

The calculator uses matrix operations (Gaussian elimination) to determine the solution. It converts the equations into a matrix form and solves step by step.

What if my system has no solution?

If the system is inconsistent (has no solution), the calculator will notify you. This can occur when the equations represent parallel lines.

Can I solve non-linear equations with this tool?

No, this calculator only solves linear systems of equations. Non-linear systems require different methods.

How do I enter equations?

Enter equations in the format ax + by + cz = d, where a, b, and c are coefficients, and d is a constant. For example:

  • 3x + 2y = 12
  • -x + 4y = 8
