Formula used
Solves a₁x + b₁y = c₁ and a₂x + b₂y = c₂ using Cramer's rule (determinants).
Example: x + y = 10 and 2x − y = 5 → x = 5, y = 5.
How to use this calculator
- Enter a₁ (eq. 1, coeff. of x), b₁ (eq. 1, coeff. of y), c₁ (eq. 1, result), a₂ (eq. 2, coeff. of x), b₂ (eq. 2, coeff. of y), c₂ (eq. 2, result).
- Press Calculate to see your result instantly.
FAQ
Frequently asked questions
What method is used to solve the system?
Cramer's rule, which uses determinants to solve for x and y directly.
What if there's no unique solution?
If the two equations are parallel (or identical), the calculator shows an error since there's no single solution.
Can I solve three or more equations?
This tool handles exactly two equations with two unknowns.
What do the coefficients represent?
Each equation is in the form (coefficient of x) × x + (coefficient of y) × y = (result).
