Write the System of Equations Associated with the Augmented Matrix $$\left[ \begin{array} { r r r | r } 5 & 6 & - 9 & - 9 \\6 & 5 & 0 & - 4 \\- 3 & 0 & 3 & 7\end{array} \right]$$

question 318

Multiple Choice

Write the system of equations associated with the augmented matrix. Do not solve.
- $$\left[ \begin{array} { r r r | r } 5 & 6 & - 9 & - 9 \\6 & 5 & 0 & - 4 \\- 3 & 0 & 3 & 7\end{array} \right]$$

• A) \(5 x + 6 y - 9 z = - 9\)
• \(\begin{array} { r r } 6 x + 5 y & = - 4 \\ - 3 x + 3 y & = 7 \end{array}\)
• B) \(5 x + 6 y - 9 z = - 9\)
• \(6 x + 5 z = - 4\)
• \(- 3 x + 3 y = 7\)
• C) \(5 x + 6 y - 9 z = - 9\)
• \(6 x + 5 y - 4 z = 0\)
• \(- 3 x + 3 y + 7 z = 0\)
• D) \(5 x + 6 y - 9 z = - 9\)
• \(6 x + 5 y = - 4\)
• \(- 3 x \quad + 3 z = 7\)
