Solve the System, If Possible $\left\{ \begin{array} { l } 8 x + 5 y + 6 z = 22 \\4 x - 9 y + 2 z = 78 \\7 x - 7 y - 10 z = 57\end{array} \right.$

Multiple Choice

Solve the system, if possible. $\left\{ \begin{array} { l } 8 x + 5 y + 6 z = 22 \\4 x - 9 y + 2 z = 78 \\7 x - 7 y - 10 z = 57\end{array} \right.$

A) x = -1, y = 12, z = -2
B) x = 5, y = -6, z = 2
C) x = -5, y = 6, z = -2
D) x = -5, y = 5, z = -2
E) no solution; inconsistent system
