Transferred 4040

The cowboy has 25 horses in two pens. He transferred 5 from the first to the second, then sold 7 horses from the second. How many horses were originally in the first pen? In the first enclosure, there were just 2 times more horses than in the second enclosure. How many horses were in the second pen?

Correct answer:

a =  17
b =  8

Step-by-step explanation:


a+b=25
(a-5) = 2·(b+5-7)

a+b = 25
a-2b = 1

Row 2 - Row 1 → Row 2
a+b = 25
-3b = -24


b = -24/-3 = 8
a = 25-b = 25-8 = 17

a = 17
b = 8
