For what value of a, if any, will the following system of equation in x, y and z have a solution?
2x + 3y = 4
x + y + z = 4
x + 2y – z = a
-
- any real number
- 0
- 1
- There is no such value
- any real number
Correct Option: B
Augmented matrix is
R1 → R1 – 2R2
R3 → R3 – R2
R1 → R1 – R3
will have solution if a = 0
as Rank of [A] = Rank of Augmented [A]
