Study Notes

Cramer's Rule

Cramer's Rule is a method for solving systems of linear equations.
Cramer's Rule can only be used for systems of linear equations with the same number of equations as variables.
The determinant of the coefficient matrix must not be zero for Cramer's Rule to apply.
The solution for each variable is found by replacing the corresponding column of the matrix with the constant vector.
