Algebra 48 - A Geometrical View of the Elimination Method

The video explores systems of linear equations in two and three variables, highlighting their geometric interpretations. It explains how adding equations in three variables results in planes that intersect along lines, similar to lines in two-variable systems. The video also covers the geometric visualization of variable elimination, showing how resulting planes can be oriented around intersection lines. Consistency in variable elimination is discussed, demonstrating why the same results are obtained regardless of the equations used. The video concludes with potential real-world applications of these systems.
