Introducing an equality sign, we

Where K is a proportionality constant, evaluated as

Since a 5-year-old horse is equivalent to 15-year old human,
x = 5
y = 15
we have

Thus,

Thus, for a horse who has lived 16 years
x = 16
Answer:

Step-by-step explanation:
hi,
-x+(-1)=3x+(-5)
<=>
-x-1=3x-5
<=>
3x+x = -1+5 = 4
<=>
4x=4
<=>
x=1
