In Cramer's rule, the denominator D in x=Dx/D is
- the determinant of the augmented matrix
- the determinant of the coefficient matrix
- the sum of the constant terms
- the determinant of the constants column
Answer
B. the determinant of the coefficient matrix
Solution
D is the determinant of the coefficient matrix. Dx is formed by replacing the x-column of D with the constants.
