Answer:
Explanation:
You want the equation and solution that represents "17 km is 2 km short of being half done with a hike of h kilometers."
Translating the English
We are given that the length of the hike is represented by h. Then half the hike is h/2, and 2 km short of that is (h/2) -2. We are told this is 17 km, so we can write the equation ...
17 = h/2 -2 . . . . . equation for h
Solution
Adding 2 gives ...
19 = h/2
Multiplying by 2 tells us the length of the hike:
38 = h
The length of the hike is 38 km.
