inessss [21]
Answer: x = 27, y = 23


Explanation:

x = chickens
y = horses

║ x + y = 50
║ 2x + 4y = 146

║ 2x + 2y = 100
║ 2x + 4y = 146

(2x + 4y = 146) - (2x + 2y = 100)

2y = 46
y = 23                    <span> <<<<<<<< We found y ¯\_(ツ)_/¯

Sub y = 23 into </span> x + y = 50

x+ 23 = 50

x = 50 - 23

x = 27                   <<<<<<<< We found x ¯\_(ツ)_/¯

2*52!

If Naoko needs to pick at least one, the possibilities become one less because "no card picked" possibility is ruled out
