Example:

Solve ( x + 2y + z = 1 ) ( 2x + 5y + 3z = 3 ) ( x + y + kz = 2 ) for different values of k. Solution Strategy: Convert to augmented matrix, perform row reduction. Detect inconsistent case (when k=2 leads to 0=1). Show unique solution for k≠2, infinite solutions for k=2 but with consistency. A proper solution includes a row-echelon form diagram.
