Question
If the system of equations x + ay = 0, az + y = 0 and ax + z = 0 has infinite solutions, then the value of a is
Options
A.- 1
B.1
C.0
D.no real values
Solution
Given equation x + ay = 0, qz + y = 0, ax + z = 0 has infinite solutions.
∴
= 0 ⇒ 1 + a3 = 0
or a = - 1
∴
= 0 ⇒ 1 + a3 = 0or a = - 1
