Question

find the value of k if x=1 and y=1 is a solution of equation 9kx+12ky=63​

Answer 1

Answer:3

Step-by-step explanation:

Here,

   9kx+12ky=63

 By putting the value above x=1 & y=1,

we get, 9k+12k=63   { because 9k*1=9k}

  21k = 63   { BY THE TRANSFORMING OF LHS TO RHS}

K = 63/21

HERE K = 3

Answer 2

Answer:k = 3

Step-by-step explanation:

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

9k +12k = 63

21 k =63

K = 63/ 21

K = 3
