Question

Which matrix represents the system of equations below? ⎧⎩⎨8x−9y+13z=11−8x−5y+5z=153x+4y−8z=−10

Answer 1

The matrix is:

$$
\begin{bmatrix}
8 & -9 & 13 \\
-8 & -5 & 5 \\
3 & 4 & -8 \\
\end{bmatrix}
\begin{bmatrix}
x \\
y \\
z \\
\end{bmatrix}
=
\begin{bmatrix}
11 \\
15 \\
-10 \\
\end{bmatrix}
