Question

If x = -1/2 , y = -3/2 is the solution of -2kx-4y = - 2K

then value of k is

(i) 3
(ii)-1
(iii) -2
(iv) 1​

Answer 1

iii is correct answer for the above question

Answer 2

$\huge\bold\red{Solution}$

Given:

$2x + 3y = k$

Now putting x = 2 and you = 1 in equation

$= > 2(2) + 3(1) = k$

$= > \: 4 + 3 \: = k$

$= > \: k = 7$
