Question

If (5,-3) is a solution of 12x + ky = 3k , then find the value of k . ​

Answer 1

Answer:

k = 10

Step-by-step explanation:

we have 12x + ky = 3k

let x=5 , y= -3

12*5+-3k = 3k

6k = 60

k= 60/6= 10

Answer 2

Answer:

the value of k = 10

Step-by-step explanation:

by substitution

x = 5 , y = -3

12(5) + k(-3) = 3k

so 60 - 3k = 3k

60 = 6k

60/6 = k

10 = k
