Find the value of k for which each of the following systems of equations has no solution:
3x - y - 5 = 0, 6x - 2y + k = 0 (k 0).
Given: 3x - y - 5 = 0 – eq 1
6x - 2y + k = 0 – eq 2
Here,
a1 = 3, b1 = - 1, c1 = - 5
a2 = 6, b2 = - 2, c2 = k
Here,
Given that system of equations has no solution

- k ≠ - 2× - 5
- k≠ - 10
K≠10
∴ k≠ - 10
