I believe the answer your looking for is B.. good luck my friend!
Hello!
-2x + y = 1
-4x + y = -1
You can subtract these equations from each other to eliminate y
2x = 2
Divide both sides by 2
x = 1
Put this into one of the original equations
-2(1) + y = 1
Combine like terms
-2 + y = 1
Add 2 to both sides
y = 3
The answer is D) (1, 3)
Hope this helps!
