Question

If (2,-3) 8s an solution of 3x+ky=18 then find the value of k.
​

Answer 1

Step-by-step explanation:

Let A(x,y)= A(2,-3)

3x+ky= 18

substitute the value of x and y in the given equation

3×2+k×(-3)= 18

6-3k= 18

-3k= 18-6

-3k= 12

3k= -12

k= -12/3

k= -4

Therefore, The value of k is -4
