Answer 2

Answer:

=> The value of x is 7, and y is 1.

Step-by-step explanation:

Given that:-

$2x-7y=7$     $...(i)$

$3x+y=22$    $...(ii)$

To find:- The value of the expression,

Now, multiply equation ( ii ) by 7, we get

=> $21x+7y=154$    $...(iii)$

Add equations ( i ) and ( iii ), we get

=> $23x=161$

Divide by $23$ on both the sides of the equation, we get

=> $x=7$

So, the value of x is 7.

Now, put the value of x as 7 in the equation ( i ), we get

=> $2 ( 7 ) - 7y = 7$

By further calculation, we get

=> $14 - 7y = 7$

=> $7y = 14 - 7$

=> $7y = 7$

Divide by $1$ on both sides, we get

=> $y = 1$

So, the value of y is 1.
