In a farm consisting only of horses and chickens, there are $146$ total feet. if there are $50$ animals total, how many horses are there? enter your 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                     <<<<<<<< We found y ¯\_(ツ)_/¯

Sub y = 23 into  x + y = 50

x+ 23 = 50

x = 50 - 23

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