Question 117

Multiple Choice

Use Cramerʹs rule to solve the system of equations. If D = 0, use another method to determine the solution set.
- 3x+3y+z=224x4yz=25x+y+3z=18\begin{array} { l } 3 x + 3 y + z = 22 \\4 x - 4 y - z = 2 \\5 x + y + 3 z = 18\end{array}


A) {(4,2,4) }\{ ( 4 , - 2,4 ) \}
B) {(2,4,4) }\{ ( - 2,4,4 ) \}
C) {(4,4,2) }\{ ( 4,4 , - 2 ) \}
D) Cramer's rule does not apply since D=0\mathrm { D } = 0 ;
