Answer 2

Answer:

k ≠ 6

Step-by-step explanation:

Given Equations are:

(i) kx + 2y - 5 = 0

Here, a₁ = k, b₁ = 2,c₁ = 5

(ii) 3x + y - 1 = 0

Here, a₂ = 3, b₂ = 1, c₂ = -1

Unique solution:

∴ a₁/a₂ ≠ b₁/b₂

⇒ k/3 ≠ 2/1

⇒ k ≠ 6

Thus, the given system of equations have unique solution, if k ≠ 6.

Hope it helps!
