In this video explaining second example of Cramer's rule. Find the z value also. This example is very easy. Cramer's rule can be useful for small systems of equations but it becomes computationally inefficient for larger systems since it requires computing n+1 determinants. Other methods such as Gaussian elimination are often used instead.
