x = -1
Step-by-step explanation:
5x + 5 = 0
Subtract 5 from each side
5x+5-5 = 0-5
5x = -5
Divide by 5 on each side
5x/5 = -5/5
x = -1

Answer:
So average of a set of values is the sum of given values divided by the number of values
So, in this case the given values are 12, 9 , 4 , 8 ,7 and x (letting the 6th friend's time be x)
so the average will be:
(12 + 9 + 4 + 8 + 7 + x)/6 = 9
40 + x = 54
x = 54 - 40
x = 14 hours
