Question

If the point (2, -1) lies on graph of equation
3x + ky=4 then find value of k​

Answer 1

3x+ky=4

3×2+K×-1=4

k=6-4

k=2

Answer 2

Answer:

k = 2

Step-by-step explanation:

3x+ky= 4

it is given that x=2 and y = -1

therefore we will put the values on their suitable places

=> 3×2+k×(-1)= 4

= 6+( -k )=4

= 6-k = 4

= -k = 4-6

= k = - (- 2)

= k = 2
