Question

x=-2,y=1/4 are the solution of the equation -2x+ky=4 find k

Answer 1

Answer:

0

Step-by-step explanation:

-2x+ky=4

x=-2,y=1/4

=> -2(-2)+k(1/4)=4

4+k/4=4

k/4=4-4

k/4=0

k=0

Answer 2

SOLUTION:-

Given value,

x= -2

y= 1/4

So, putting the value in this equation;

-2x +ky= 4

$= > - 2( - 2) + k( \frac{1}{4} ) = 4 \\ \\ = > 4 + \frac{k}{4} = 4 \\ \\ = > 16 + k = 16 \\ \\ = > k = 16 - 16 \\ \\ = >k = 0$

hope it helps ☺️
