QuestionConsider the system of linear equations shown below: $$\begin{array}{c} 2 x+9=-4 y \\ -x-y=2 \end{array}$$
Create the coefficient matrix, $D$

Studdy Solution
Form the coefficient matrix $D$ using the extracted coefficients:
$$D = \begin{bmatrix} 2 & 4 \\ -1 & -1 \end{bmatrix}$$
This matrix represents the coefficients of $x$ and $y$ in the system of equations.
