Question

If x=1, y=1 is a solution of the equation 9kx + 12 ky =63, then find the value of K


plz it's urgent answer fast​

Answer 1

Answer:

k = 3

Step-by-step explanation:

If x = 1 and y = 1 is a solution of 9kx + 12ky = 63, then must satisfy the conditions of the equation.

Hence, substituting the solutions,

9k(1) + 12k(1) = 63

9k + 12k = 63

21k = 63

k = 63/21

k = 3

Hence,

k = 3, when x = 1 and y = 1 are solutions of 9kx + 12ky = 63

Hope it helped and believing you understood it........All the best

Answer 2

9kx + 12ky = 63

9k + 12k = 63 (x=1 y=1)

21k = 63

k= 63/21

k=3
