One of the most common applications of square matrices is to solve systems of linear equations. Solving linear systems using matrix algebra is more efficient than hand calculating the systems using substitution methods; this is especially true when dealing with systems of 3 or more variables. Two matrix algebra methods include: row reducing and finding the inverse.
