Solve linear equations. Input coefficients to compute $x, y, z$ values and visualize the step-by-step matrix determinants.
How to use
- Select either the 2-variable or 3-variable equation tab.
- Input the coefficients and constant terms for all linear equations.
- Review the calculated matrix determinants ($D, D_x, D_y, D_z$) and the resolved solution.
FAQ
- What is Cramer's rule?
- Cramer's rule is an explicit formula for the solution of a system of linear equations with as many equations as unknowns, valid whenever the system has a unique solution using determinants.
