By making the linear equations into matrices, it would be easier to work on finding the unknowns of many equations. Although the most common way to go through the determinants is by using the basket method of the Cramer's rule, expansion of the determinants (using Laplace expansion) is also possible. This method breaks down large determinants to smaller ones.
Matrices and determinants look alike only that instead of a bracket, determinants use bars. Also, determinants have values.
