WebMar 26, 2016 · You can't use Cramer's rule when the matrix isn't square or when the determinant of the coefficient matrix is 0, because you can't divide by 0. Cramer's rule is most useful for a 2-x-2 or higher system of linear equations. To solve a 3-x-3 system of equations such as. using Cramer's rule, you set up the variables as follows: WebDeterminants and matrices, in linear algebra, are used to solve linear equations by applying Cramer’s rule to a set of non-homogeneous equations which are in linear form.Determinants are calculated for square matrices only. If the determinant of a matrix is zero, it is called a singular determinant and if it is one, then it is known as unimodular.
