Answer:
If the function is
A(n) = 4n -25
and we wish to get the inverse function N(a)
We let
A(n) = a
n = N(a)
Plugging in the values
a = 4 N(a) - 25
Arranging the equation:
4 N(a) = a + 25
N(a) = (a + 25) /4
The answer is
N(a) = (a + 25) /4

Multiply the first equation by -1
-3x-y=-4
2x+y=5
Add them up 
-x=1
So x=-1
And y=7 
So the first option is correct
