To solve this problem you must apply the proccedure shown below:
1. You have that the ages of three friends are consecutive integers and the sum of their ages is
. Therefore, let's call the age of the youngest friend
, the middle age
and the age of the oldest
. Then, you can write the following expression and solve for
:
![x+(x+1)+(x+2)=57\\ 3x+3=57\\ x=18](https://tex.z-dn.net/?f=%20x%2B%28x%2B1%29%2B%28x%2B2%29%3D57%5C%5C%203x%2B3%3D57%5C%5C%20x%3D18%20)
2. Therefore, the age of the oldest friend is:
![x+2=18+2=20](https://tex.z-dn.net/?f=%20x%2B2%3D18%2B2%3D20%20)
The answer is:
years old.
