John can walk 4 miles per hour
Answer:x=4
Step-by-step explanation:
You can split this up into two equations
x-4=0
x+5=0
To solve each:
x-4=0
Add 4 to each side
x=4
------------
x+5=0
Subtract 5 from each side
x=-5
So your two solutions are -5 and 4 but you want the positive one so the answer is x=4
