Multiple Choice

Write the system of linear equations represented by the augmented matrix. Use x, y, z, and, if necessary, w for the
variables.
- $$\left[ \begin{array} { r r r r | r } 6 & 1 & 0 & 8 & - 6 \\- 1 & 3 & 1 & 0 & 7 \\7 & 0 & 0 & 5 & - 4 \\0 & 4 & 0 & - 4 & 10\end{array} \right]$$

• A)
• \[\begin{array} { r }
• 6 x + y + 8 w = - 6 \\
• - x + 3 y + z = 7 \\
• 7 x + 5 w = - 4 \\
• 4 y - 4 w = 10
• \end{array}\]
• B)
• \(6 x + y + z + 8 w = - 6\)
• \(- x + 3 y + z + w = 7\)
• \(7 x + y + z + 5 w = - 4\)
• C)
• \(\begin{array}{r}
• 6 x+y+8 w=-6 \\
• x+3 y+z=7 \\
• 7 x+5 w=-4 \\
• 4 y+4 w=10
• \end{array}\)
• D)
• \(\begin{array}{r}
• 6 x+y+8 z=-6 \\
• -x+3 y+z=7 \\
• 7 x+5 y=-4 \\
• 4 x-4 y=10
• \end{array}\)
