    If \[x=-2\] and \[y=3\] is the solution of the equation\[3x-5y=k\], find\['k'\].

    A)  \[-21\]                          

    B)  \[-9\]               

    C)  \[-18\]              

    D)         \[19\]               

    Correct Answer: A

    Solution :

    Given that,\[x=-2\]and y = 3 is the solution of \[3x-5y=k,\] we have \[k=3\left( -2 \right)-5\left( 3 \right)=-\text{ }21\]
