Answer 2

Given:-

• x = 2 and y = 1 is a Solution of the equation 2x + 3y = k.

To Find:-

• The value of k .

Answer :-

If x = 2 and y = 1 is a solution of the linear equation then , on putting the values we get

⇒ 2x + 3y = k

⇒ 2x + 3y - k = 0

⇒ 2*2 + 3*1 - k = 0

⇒ 4 + 7 - k = 0

⇒ 11 - k = 0

$\boxed{\bf \implies k = 11}$

Hence the value of k is 11.

$\Large{\boxed{\pink{\sf Value \:of\:k\:is\:\boxed{11}}}}$
