Question 64

Multiple Choice

Solve the system. If a system has one unique solution, write the solution set. Otherwise, determine the number of solutions to the system, and determine whether the system is inconsistent, or the equations are dependent.
- 2x+2y+5z=192x+2y+3z=136x+6y+11z=44\begin{array} { l } 2 x + 2 y + 5 z = - 19 \\2 x + 2 y + 3 z = - 13 \\6 x + 6 y + 11 z = - 44\end{array}


A) No solution; inconsistent
B) Infinitely many solutions; dependent
C) {(1,2,5) }\{ ( 1,2 , - 5 ) \}
D) {(1,1,4) }\{ ( 1,1 , - 4 ) \}
