Question 445

Multiple Choice

Solve the system in terms of the arbitrary variable x.
- x−3y+z=353x−y−z=21\begin{array} { l } x - 3 y + z = 35 \\3 x - y - z = 21\end{array}
3x−y−z=213 x - y - z = 21

B) {(x,x−14,2x−7) }\{ ( x , x - 14,2 x - 7 ) \}
C) {(0,−14,−7) }\{ ( 0 , - 14 , - 7 ) \}
D) {(x,x−14,2x) }\{ ( x , x - 14,2 x ) \}
