Question

find the value of k if x=2y=1 is a solution of the equation 2x+3y=k​

Answer 1

Given: The value of x = 2, y = 1.

To find: The value of k.

Solution:

• Now we have given the equation:

                 2x + 3y = k​

• We have given the values of x and y as x = 2, y = 1.

• Putting these values in the given equation, we get:

                 2(2) + 3(1) = k

• Now solving this, we get:

                 k = 4 + 3

                 k = 7

Answer:

                So the value of k is 7.

Answer 2

Answer:

=> The value of k = 7

Step-by-step explanation:

Given that:-

$2x+3y=k$      $...(i)$

If $x=2,y=1$

To find - Tha value of k,

In order to find the value of k,

Plug the given values in the equation ( i ) we get,

As we have,

=> $2x+3y=k$  

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

=> 4 + 3 = k

=> 7 = k

Hence, the value of k is 7.
