Matrices simplify the process of solving systems of equations using methods like row reduction.

Front

What does it mean for two equations to be independent?

Back

Independent equations have a unique solution and are not multiples of each other.

What is the row echelon form of a matrix?

Back

It is a form where all non-zero rows are above any rows of all zeros, and leading coefficients are to the right of leading coefficients in the rows above.
