Answer
$\left\{\begin{array}{l}
2x-3y=8\\
5x+6y=11
\end{array}\right.$
Work Step by Step
$D$ is the determinant of the matrix of coefficients of the unknowns,
$D_{x}$ is obtained from $D$ by replacing the first column with the column of constants.
This gives us enough information to write
$\left\{\begin{array}{l}
2x-3y=8\\
5x+6y=11
\end{array}\right.$
