5 - x = 12
We're essentially just trying to get "x" onto its own side.
So, simply subtract 5 from both sides.
-x = 12 - 5
Simplify.
-x = 7
Now, divide both sides by -1.
x = -7

Answer:
400 ft
Step-by-step explanation:
Let the distance traveled = d
Let the time taken = t
d α t^2
d = kt^2
k = d /t^2
When d = 100 and t = 2.5secs
k = 100/ (2.5)^2
k = 16
d = 16t^2
When t = 5secs
d = 16(5)^2
d = 16 * 25
d = 400 ft
