<u>Answer:</u>

The answer D is correct.

<u>Step-by-step explanation:</u>

-x + y = 8 ⇒ ( 1 )

7x + 3y = - 16 ⇒ ( 2 )

y = 8 + x ⇒ ( 3 )

Let us take equation 2 and let us replace y with (8+x).

Let us solve and find the value of x.

7x + 3y = -16

7x + 3 ( 8 + x ) = - 16

7x + 24 + 3x = -16

10x + 24 = -16

10x = -16 - 24

10x = -40

<h3>x = (-4)</h3>

And now let us find the value of y.

For that, let us use equation (3)

Here, we have to replace x with -4 to find the value of y.

y = 8 + x

y = 8 - 4

<h3>y = 4</h3>

Now we have to the answers in the form ( x , y )

Let us write.

( x , y ) ⇒ ( -4 , 4 )

Let me know if you have any other questions. :-)
