Question

If (8,-2) is one of the solution of 3x+ky=8, find the value of k.​

Answer 1

Answer:

The value of k is 8

Step-by-step explanation:

3x+ky=8

the given point is (8,-2). So, x = 8 and y = -2

put value of x and y in equation.

3(8) + k(-2) = 8

24 -2k = 8

2k = 24-8

2k = 16

k = 16/2

k = 8

Answer 2

It is given that x=8 and y=(-2) is a factor of the polynomial 3x+ky=8

So, 3x+ky-8=0

or, 3×8+k×(-2)-8=0

or, 24-8-2k=0

or, -2k= -16

or, k= -16÷ -2

or, k=8
