What is the Cramer's Rule?

The Cramer's Rule uses determinants to solve a linear system of equations.

Cramer's Rule

Sometimes using matrix algebra or inverse matrices to find the solution to a system of linear equations can be tedious. Sometimes it is more convenient to use Cramer's Rule and determinants to solve a system of equations. Finding determinants becomes much more difficult with higher dimensions, and so Cramer's Rule is better for smaller systems of linear equation.
