Question

if x= 1/2 , y= -1 is the solution of 2kx - 3y = 4K find the value of k​

Answer 1

Given:-

$x = \frac{1}{2} ,y = - 1 \: is \: the \: solution \: of \: 2kx - 3y \: = 4k$

To find :-

Value of k

Solution :-

Since ,

$x = \frac{1}{2} ,y = - 1 \: is \: the \: solution \: of \: 2kx - 3y \: = 4k$

Therefore

$x = \frac{1}{2} ,y = - 1 \: satisfy \: \: the \: given \: linear \: equation$

So

➵ $2 \times k \times \frac{1}{2} - 3 \times - 1 = 4k$

➵ $k + 3 = 4k$

➵ $3 = 4k - k$

➵ $3 = 3k$

➵ $\frac{3}{3} = k$

➵ $1 = k$

So value of k = 1

Answer 2

Answer:

here is your answer

2k1/2-3×(-1) = 4k

1/2-3=2k

3= k
