Cramer's Rule Explained With D, Dx, Dy
This animation visualizes how Cramer's Rule solves a system of two linear equations by building determinants step by step. It shows how the main determinant D is formed from coefficients, then how Dx and Dy are constructed by swapping in the constant terms, with matching colors and highlights linking each matrix to its determinant value. Useful for algebra and linear algebra students learning to solve systems without substitution or elimination.

The prompt that made it
There is a layout problem. The animation should Start from more above to cover properly all the scene in screen. Add some explanation visual like how Dx,Dy and D calculated show it with visual effect.
Make the next one in this series
- Show Cramer's Rule extended to a 3x3 system with x, y, and z
- Compare Cramer's Rule side by side with Gaussian elimination on the same system
- Visualize what it means geometrically when the determinant D equals zero
