4y+2x=14 ==> multiply this 1st equation by (-1) => -4y-2x=-14
Now add it up to the 2nd equation
-4y-2x=-14
2y+2x=10
-------------- And now add them up
-2y +0x=-4
==> -2y=-4==> 2y = 4 & y=2
Last step: plug y into any equation & you will find x=3

Answer:
1 mile
Step-by-step explanation:
We can write a ratio to solve
We know 1 hour is 60 minutes
1/6 mile x miles
------------ = ---------------
10 minutes 60 minutes
Using cross products
1/6 miles * 60 minutes = 10 minutes * x
10 = 10x
Divide by 10
1 = x
1 mile
