Question

For what value of k, if the pair of equations

4x – 5y =10, 2x + ky = 11, has no solution?​

Answer 1

Step-by-step explanation:

a1 / a2 = b1 / b2 is not equal to c1 / c2

a1 = 4 , b1 = -5 , c1 = - 10

a2 = 2 , b2 = k , c2 = -11

4 / 2 = -5 / k is not equal to -10 / 11

4k = - 10

k = -10 / 4

k = - 5 / 2
