Enter the six coefficients of both equations and x and y are found with Cramer’s rule.

How to Use Two-Variable System of Linear Equations Solver

  1. 1
    First equationa₁, b₁ and c₁ of a₁x + b₁y = c₁.
  2. 2
    Second equationa₂, b₂ and c₂. Negatives are fine.
  3. 3
    Read the solutionx and y if there is one solution; otherwise "no solution" or "infinitely many".

Examples

2x + 3y = 13, x − y = −1
Input: 2, 3, 13 / 1, −1, −1
Result: x = 2, y = 3
x + y = 10, 2x + 4y = 28
Input: 1, 1, 10 / 2, 4, 28
Result: x = 6, y = 4

Common Use Cases

  • Checking simultaneous equation homework
  • Prices or quantities that satisfy two conditions
  • Mixture ratio problems

Frequently Asked Questions (FAQ)

What does "no solution" mean?

The two lines are parallel and never meet. Infinitely many solutions means both equations describe the same line.

What about three unknowns?

This tool handles two.
