Question

K X + 2 Y =5,3x+y=1has unique solution if k is​

Answer 1

Answer:

If k ≠ 6 i.e. k has any real values except 6.

Step-by-step explanation:

Two system of equations have unique solution if a₁ / a₂ ≠ b₁ / b₂

Here a₁ = k , a₂ = 3 , b₁ = 2 , b₂ = 1

⇒ k / 3 ≠ 2 / 1

⇒ k ≠ 6

∴ k should have any real values except 6 so that the system of equations have a unique solution.
