Cramer's Rule 2x2 Matrices | Part 01

This is lecture is about Cramer's rule to solve a system of linear equations with two variables. You will learn about Cramer's rule 2x2 and how to use Cramer's rule to solve a system of equations.
Q: How to use Cramer's rule to solve a system of linear equations?
Ans: In matrices, Cramer's rule is used to solve a system of linear equations. This method is used to find the value of x and y variables using matrices. Firstly, we form 2 by 2 or 3 by 3 matrices. Secondly, we find the determinants of these matrices. Once, the determinants are known, we can then find the value of x, y and z variables easily.
Therefore, remember that Cramer's rule in algebra is also used to find value of variables.
To learn more about Cramer's rule and system of linear equations, watch this lecture till the end.

This is not the linear equation , at least you should able to identify by yourself.
