Question

If (3,-2) is a solution of the equation 2x − ky = 14 ,find the value of k

Answer 1

Answer  

k= - 4

Step-by-step explanation:

The equation is 2x - ky=14

The solution of the equation is (3,-2)

Now, putting 3 in place x and -2 in place of y, we get-

2*3 - k*(-2) = 14

6 - 2k = 14

-2k = 14 - 6 ( subtracting 6 from both sides)

-2k = 8

k = 4

thank you

Answer 2

Answer:

2x+Ky=−14

−7

x

+

−14/k

y

=1

Using intercept form, we get

y intercep t=

K

−14

=−2

So, K=7
