Kramer's method (Kramer's rule) is a method of solving quadratic systems of linear algebraic equations with a nonzero determinant of the main matrix (at the same time, such equations have a unique solution). Kramer's rule expresses the solution through the determinants of the square matrix of coefficients and matrices obtained by replacing one column of the matrix of coefficients with a column vector of the…
