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 h represent the number of horses.

Which equation represents the situation?




2h + 2 = 16

2(h+2)=16

h + 2 = 16

2h−2=16

Answer 1

2h-2=16

Explanation:

Let

h -----> the number of horses

c ----> the number of a cows

we know that

h+c=16 -----> equation A

h=c+2

c=(h-2) ----> equation B

Substitute equation B in equation A and solve for h

h+(h-2)=16

2h-2=16

2h=16+2

2h=18

h=9

therefore

The equation that represent the situation is

2h-2=16
