This animation introduces Gaussian elimination through an economics-flavored example with four equations and three unknowns. It shows how to translate equations into a coefficient matrix, apply row operations to simplify the system, and interpret the result as a unique solution, no solution, or infinitely many solutions. Useful for students learning linear algebra fundamentals and teachers introducing matrix methods for solving systems of equations.

Revise the visual design of this video. Preserve the mathematics and narration. Use a modern, restrained university teaching style: - Soft off-white background. - Clean sans-serif font for titles and labels. - Keep standard mathematical typesetting for equations. - Smaller title aligned at the top left. - Larger equations arranged as one compact, aligned system. - Align corresponding variable columns and equals signs. - Place “4 equations · 3 unknowns” as a small label near the system. - Use dark charcoal text and one muted blue accent. - Highlight only the variable or coefficient currently being explained. - Reveal equations progressively with subtle transitions. Keep consistent margins and a clear visual hierarchy. Avoid oversized headings and widely scattered elements.
