If the system of linear equations
2x + 3y - z = - 2
x + y + z = 4
x-y+| 
|z = 4 
-4
where 
, has no solution, then
A
= 7
B
= -7
C
= 8
D
=1
Text Solution
Verified by ExpertsThe correct answer is:
B
….(1)
System:
….(2)
x + y+z = 4 ....(3)
....(4)
Eliminating y from equal (2) & (3) we get
x + 4z = 14 ....(5)
(3) + (4) 
...(6)
Clearly for 
= -7, system is inconsistent.
