Quizplus · Accepted Answer

Cramer's rule applies because the determinant $D$ of the coefficient matrix is non-zero ($D = 9(3) - (-5)(6) = 27 + 30 = 57$), allowing for the solution $(0, -1)$ to be found.

Use Cramerʹs Rule to Solve the System of Equations 9x+6y=−6−5x+3y=−3\begin{array} { l } 9 x + 6 y = - 6 \\- 5 x + 3 y = - 3\end{array}9x+6y=−6−5x+3y=−3​
