Answer:

Option A is the correct answer.

Step-by-step explanation:

First, look at the second equation. Get s and r onto the same side.

For simplicity, I will use x for r and y for s

Multiply the first equation by 3, and multiply the second equation by -4.

3(2x+8y=−4)

−4(7x+6y=8)

Becomes:

6x+24y=−12

−28x−24y=−32

Add these equations to eliminate y:

−22x=−44

x=2=r

Now we substitute this back in for the original equation

(2)(2)+8y=−4

8y=-8

y=-1=s

Option A is the correct answer.
