Question

the value of a for which the system of equation ax+y+z=0 , x+ay+z=0 , x+y+z=0 possess non null solution

Answer 1

Answer:

option (i) is correct answer

Answer 2

Answer:

♠ The correct option is D.

Explanation:

Here,

For a = 1, the equations become

x + y + z = 1

x + y + z = 1

x + by + z = 0

These equations give no solution for b = 1

Therefore, S is singleton set.
