Question

If (2,3) is a solution of linear equation 2x+3y=k then,the value of k is????

Answer 1

let x=2,y=3
then 2*2+3*3=k
4+9=k
k=13

Answer 2

$2x + 3y = k \\ x = 2 \: \: \: \: and \: \: \: y = 3 \\ then \: \: \\ putting \: the \: values \: of \: x \: and \: y \: in \: the \: equation \\ \\ 2(2) + 3(3) = k \\ 4 + 9 = k \\ k = 13$
$hope \: helps$
