Question

6. Find the value of k if x =2, y=1 is a solution of the equation
2(x - 1) - 7(y-2) = k​

Answer 1

$\huge{\mathfrak{answer}}$

Given equation:

2x+3y=k

Now putting x=2 and y =1 in equation

⇒2(2)+3(1)=k

⇒4+3=k

⇒k=7

Answer 2

${\huge{\fbox{\bf{Answer}}}}$

$2(x - 1) - 7(y - 2) = k$

${\underline{\sf{put \: x = 2 \: and \: y = 1 \: in \: the \: above \: equation}}}$

$2( 2- 1) - 7(1 - 2) = k$

$2(1) - 7( - 1) = k$

$k = 2 + 7$

${\bold{\underline{\underline{\sf{k = 9}}}}}$
