Question

Find the value of K if x=2,y=1 is a solution of 2x+3y=K

Answer 1

$hey \: mate \\ here \: is \: your \: answer \\ \\ x = 2. \: y = 1 \: (given) \\ putting \: these \: values \: on \: equation \\ 2x + 3y = k \\ 2(2) + 3(1) = k \\ 4 + 3 = k \\ 7 = k \\ k = 7 \: i \: hope \: its \: helpful$

Answer 2

Hey here is the answer
$2x + 3y = k$
$2(2) + 3(1) = k \\ 4 + 3 = k \\ k = 7$
