Cramer's Rule Calculator

Solve a 2×2 or 3×3 system of linear equations with determinants — get D, Dx, Dy, Dz, the solution, a graph, and the full step-by-step working.

Cramer's rule:  x = Dx / D,  y = Dy / D,  z = Dz / D
x +y =x +y =

Enter the coefficients and the constants. Cramer's rule needs a non-zero determinant for a unique solution.
