Write the System of Linear Equations Represented by the Augmented $\left[ \begin{array} { r r r | r } 6 & 9 & 6 & - 2 \\ 2 & 0 & 7 & 4 \\ 6 & 8 & 0 & 2 \end{array} \right]$

question 68

Multiple Choice

Write the system of linear equations represented by the augmented matrix. Use x, y, z, and, if necessary, w for the
variables.
- $\left[ \begin{array} { r r r | r } 6 & 9 & 6 & - 2 \\ 2 & 0 & 7 & 4 \\ 6 & 8 & 0 & 2 \end{array} \right]$

• A) \(6 x + 9 y + 6 z = - 2\)
• \(2 x + 7 z = 4\)
• \(6 x + 8 y = 2\)
• B) \(6 x - 9 y + 6 z = - 2\)
• \(2 x + 7 z = - 4\)
• \(6 x + 8 y = - 2\)
• C) \(6 x + 9 y + 6 z = - 2\)
• \(2 x + 7 z = 4\)
• \(6 x + 8 z = 2\)
• D) \(6 x + 9 y + 6 z = - 2\)
• \(2 x + y + 7 z = 4\)
• \(6 x + 8 y + z = 2\)
