Well, lets start with what you know. We know that 5 horse years is equal to 15 human years. If the horse is 16, 5 times 3.2 equals 16.
5 year old horse/ 15 year old human
16 year old horse/ ? human?
3.2 times 5 is 16. To find the answer, do 3.2 times 15, or 320% of 15. Three times fifteen is 45. 20% of 16 is 3.2. 45 plus 3.2 is 47.2! Did this help you?
Answer:

(-7)^2 = 49
Add it
x^2 -14x +49
Take the -7
( x-7)^2
The answer is : 5.29411764706
The answer when rounded: 5.29 or 5.3
I found the answer by simply dividing 45/8.5 - Remember that per means division!
