Cramer's Rule Visualized

This animation shows how Cramer's Rule solves systems of linear equations using determinants. It visually walks through replacing columns of the coefficient matrix with the constants vector, computing determinants geometrically as areas or volumes, and forming the ratio that gives each variable's value. Useful for algebra and linear algebra students learning matrix methods for solving equations, and for teachers introducing determinants as a practical problem-solving tool beyond abstract computation.
