Question

A problem states: "There are 2 more horses than cows in a field. There are 16 animals in the field in all. How many horses are there in the field?"

Let c represent the number of cows.

Which equation represents the situation?




2(c+2)=16

c + 2 = 16

2c + 2 = 16

2c−2=16

Answer 1

Let c represent the number of cows

Let h represent the number of horses

There are 2 more horses than cows in a field

⇒there are extra two horses are always than cows

⇒ horses-cows =2

⇒ hourses=2+cows

⇒ h =2+c

There are 16 animals in the field in all.

⇒ h +c=16

⇒ (2+c)+c=16

⇒ 2+2c=16

⇒ 2+2c-2=16-2

⇒2c=16-2

⇒ 2c=14

c=7
