Question

4x3y=19,4x-3y=-11 answer=（k,5）k=？​

Answer 1

$4K + 15 = 19 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: (equation \: 1 )$

$4K - 15 = - 11 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: (equation \: 2)$

$Adding\: both\:the\: equations\:we\:will\:get\:K = 1$

$\therefore \: The\:value\:of\:K\:is\:1$
