Question

Q2. The value of k for which the lines 3x+4y=5,5x + 4y = 4 and kx + 4y = 6 meet at a point ​

Answer 1

Answer:

It is given that the lines 3x + 4y = 5, 5x + 4y = 4 andλx + 4y = 6 meet at a point.  In other words, the given lines are concurrent.  ⇒ 3(- 24 + 16) – 4 (- 30 + 4λ) – 5 (20 – 4 λ) = 0  ⇒ - 24 + 120 – 16 λ – 100 + 20 λ = 0  ⇒ 4 λ = 4  ⇒ λ = 1Read more on Sarthaks.com - https://www.sarthaks.com/1154791/the-value-of-for-which-the-lines-3x-4y-5-5x-4y-4-and-x-4y-6-meet-at-a-point-is
