What is the System of Equations Solver?
Solve two equations with two unknowns (x and y) or three equations with three unknowns (x, y and z). Just type the coefficients – the solver uses Cramer’s rule, shows the determinants and checks the answer by substituting it back.
How to use the System of Equations Solver
- Choose 2 or 3 variables.
- Enter the coefficients of each equation in the form ax + by (+ cz) = d.
- Read the solution and the check.
Example
2x + 3y = 13 and x − y = −1 gives x = 2, y = 3.
No unique solution?
If the main determinant is 0, the lines (or planes) are parallel or the same – there is either no solution or infinitely many.
This System of Equations Solver is 100% free, needs no signup and runs privately in your browser – on phone, tablet or computer.
