Simple, use the process of elimination to figure this out:
4x-y=2
2x+9y=-12
Convert these, to be able to find either x or y.
2(4x-y=2) 8x-2y=4 multiply by 2.
then
4(2x+9y=-12) 8x+36y=-48
Which makes them
8x-2y=4
-
8x+36y=-48
-38y=52
This simplified makes it y= -26/19.
Then plug y back into the original equation
4x-y=2
4x-(-26/19)=2
Making it x= 3/19.
Thus your Point of Intersection is at (3/19, -26/19)

None of the above.........
Answer: The distance in the map is 19 inches.
Step-by-step explanation:
On the map. 2 inches represent an actual distance of 64 miles.
The actual distance between town A and town B is equal to 608 miles, we need to divide this distance into groups of 64 miles.
N = 608/64 = 9.5
And each one of those 9.5 groups is represented with 2 inches in the map, then the distance in the map is:
d = 9.5*2 inches = 19 inches.
