    AnsweR :-

    2x + 3y = k

    x = 2  \:  \:  \:  \: y = 1

    \implies2(2) + 3(1) = k

    \implies4 + 3 = k

    \implies7 = k

    Procedure :-

    \implies This question is from the linear equation, as we can see that we have to find the value of k by equating the Polynomial.

    \implies We can also see that we are given the vues of x and y that are 2 and 1 respectively. Then we will put the 2 and 1 in place of x and y and then we will equate it. And hence the value of k is 7 .
