Determinants and cramer's rule

WebCalculate a determinant of the main (square) matrix. To find the 'i'th solution of the system of linear equations using Cramer's rule replace the 'i'th column of the main matrix by solution vector and calculate its determinant. Then divide this determinant by the main one - this is one part of the solution set, determined using Cramer's rule. WebExample 1.
