Cramer's Rule for a 2x2 System
This animation walks through solving 2x + 3y = 4 and x - y = 7 using Cramer's Rule. It shows how to build the coefficient matrix, compute the main determinant, then form Dx and Dy by swapping columns with the constants. Each determinant is calculated step by step with color-coded highlights, culminating in clean formulas for x and y. Useful for algebra students learning matrix-based methods for solving linear systems.
