Question 340

Multiple Choice

Write the system of equations associated with the augmented matrix. Do not solve.
- [−89855−608−80−3−3]\left[ \begin{array} { r r r | r } - 8 & 9 & 8 & 5 \\ 5 & - 6 & 0 & 8 \\ - 8 & 0 & - 3 & - 3 \end{array} \right]


A)
−8x+9y+8z=55x−6y=8−8x−3y=−3\begin{array}{l}-8 x+9 y+8 z=5 \\5 x-6 y=8 \\-8 x-3 y=-3\end{array}


B) −8x+9y+8z=55x−6y=8−8x−3z=−3\begin{array}{cc}-8 x+9 y+8 z=5 \\5 x-6 y & =8 \\-8 x-3 z=-3\end{array}

C)
−8x+9y+8z=55x−6y+8z=0−8x−3y−3z=0\begin{array}{c}-8 x+9 y+8 z=5 \\5 x-6 y+8 z=0 \\-8 x-3 y-3 z=0\end{array}

D
−8x+9y+8z=55x+−6z=8−8x−3y=−3\begin{aligned}-8 x+9 y+8 z &=5 \\5 x+-6 z &=8 \\-8 x-3 y &=-3\end{aligned}
