Question

Q2. Find the value of k for which the system of equations x + 3y = 4 and 3x + ky + 12 = 0 are inconsistent.

k = 12

k = 9

k = - 12

k = - 5​

Answer 1

Answer:

k = 9

Step-by-step explanation:

Inconsistent so a1/a2 = b1/b2 ≠ c1/c2

a1/a2 = 1/3

b1/b2 = 3/k

c1/c2 = -4/12

⅓ = 3/k ≠ -1/3

So 1/3 = 3/k

Using k = 9

we get 1/3 = 3/9 so 1/3 = 1/3

So when we assign 9 as a value for k it satisfies the equation.

Therefore, k = 9
