Question

Find the value of ‘k’ for which the system of linear equations x + 2y = 3, 5x + ky +7 =0 is inconsistent.​

Answer 1

Answer:

In consistent solutions --

a1 / a1 = b1 / b2 is not equal to c1 / c2

a1 = 1 , b1 = 2 , c1 = -3

a2 = 5 , b2 = k , c2 = 7

1/5 = 2/k is not equal to -3 / 7

k = 2×5 = 10

So.... the value of k = 10
