Question

Assertion: If $x=2,y=1$ is a solution of the equation $2x+3y=k,$ then the value of $k$ is$7.$

Reason: The solution of the line will satisfy the equation of the line.

Answer 1

Assertion: If $x=2,y=1$ is a solution of the equation $2x+3y=k,$ then the value of$k$ is$7.$

As we know, the solution of the line will satisfy the equation of the line.

So, the reason is correct.

Also putting, $x=2,y=1$ in L.H.S. of the given equation, we get

$2\left(2\right)+3\left(1\right)=4+3=7$

So, the value of$k$ is$7.$

Thus the given assertion is also correct.

Hence, both assertion and reason are true and given reason is correct explanation of assertion.
