Quizplus · Accepted Answer

The determinant of the coefficient matrix is zero, which means that Cramer's rule cannot be used and the system of equations is inconsistent.

Use Cramer S Rule to Solve the System of Equations {4x+3y=128x+6y=12\left\{ \begin{array} { l } 4 x + 3 y = 12 \\8 x + 6 y = 12\end{array} \right.{4x+3y=128x+6y=12​
