Algebra 53 - Elementary Row Operations

Professor Von Schmohawk introduces matrices and elementary row operations, including swap, scale, and pivot, to transform augmented matrices into simpler equivalent systems. These operations maintain the solutions of the original system. The lecture concludes with a preview of Gaussian elimination, which uses these operations to simplify matrices further.

Explain the concept of equivalent systems of equations.
