Alice, Bob and Carrie�s ages combined is 64 years. Alice is three years younger than Bob and Carrie is one year older than Alice. What are their ages?
**
let x=Alice's age
x+3=Bob's age
x+1=Carrie's age
**
sum of their ages=64
x+(x+3)+(x+1)=64
3x+4=64
3x=60
x=20
x+3=23
x+1=21
Alice's age=20
Bob's age=23
Carrie's age=21n
