Write a System of Linear Equations Represented by the Augmented $\left[ \begin{array} { l l l | l } 1 & 0 & 0 & 14 \\ 0 & 1 & 0 & 13 \\ 0 & 0 & 1 & 15 \end{array} \right]$

Multiple Choice

Write a system of linear equations represented by the augmented matrix. $\left[ \begin{array} { l l l | l } 1 & 0 & 0 & 14 \\ 0 & 1 & 0 & 13 \\ 0 & 0 & 1 & 15 \end{array} \right]$

A)
$\begin{array}{l}(x-1) +y+z=14 \\x+(y-1) +z=13 \\x+y+(z-1) =15\end{array}$

B)
$\begin{array}{l}x=14 \\y=13 \\z=15\end{array}$

C)
$\begin{array}{l}x+y+z=14 \\x+y+z=13 \\x+y+z=15\end{array}$

D)
$\begin{array}{l}x=-14 \\y=-13 \\z=-15\end{array}$
