Question

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

pls help​

Answer 1

Answer:

2x+3y

= 2 x 2+ 3 x 1

= 4 + 3

= 7= K please make me brainliest and follow me

Answer 2

AnsweR :-

$2x + 3y = k$

$x = 2 \: \: \: \: y = 1$

$\implies2(2) + 3(1) = k$

$\implies4 + 3 = k$

$\implies7 = k$

Procedure :-

$\implies$ This question is from the linear equation, as we can see that we have to find the value of k by equating the Polynomial.

$\implies$ We can also see that we are given the vues of x and y that are 2 and 1 respectively. Then we will put the 2 and 1 in place of x and y and then we will equate it. And hence the value of k is 7 .
