pls answer very urgent

Answer 1

Answer:

Question :-

Find the value of k, if x = 3, y = 2 , is a solution of the equation 2x + ky = 20

Required Answer :-

k = 7

Solution :-

Given :-

x = 3

y = 2

To Find :-

The value of k

Substituting the values of x and y in the equation :-

$2x + ky = 20$

$2 \times 3 + k \times 2 = 20$

$6 + 2k = 20$

$2k = 20 - 6$

$2k = 14$

$k = \frac{14}{2}$

$k = \frac{1 \cancel4}{ \cancel2}$

$k = 7$

We get the value of k as 7

Verification :-

Now let's verify our answer by substituting 7 in place of k

$2x + ky = 20$

$2 \times 3 + 7 \times 2 = 20$

$6 + 14 = 20$

$20 = 20$

$LHS = RHS$

Hence verified
