Quizplus · Accepted Answer

Cramer's rule can be used to solve a system of linear equations of two equations and two variables by finding the determinants of the coefficient matrix and the matrices obtained by replacing each column of the coefficient matrix by the constant matrix. If the determinant of the coefficient matrix is zero, then the system has no unique solution. In this case, the determinant of the coefficient matrix is 0, so there is no unique solution, and the answer is D.
