Can you define it much more simpler
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.
