Five years from ago, Zack was three times as old Aaron. Five years from now, Zack will be twice as old as aaron. How old is Aaron?
..
let x=Aaron's current age
5 years ago
x-5=Aaron's age
3(x-5)=Zack's age
5 years from now
x+5=Aaron's age
2(x+5)=Zack's age
..
Zack's age 5 years from now-Zack's age 5 years ago=10
2(x+5)-3(x-5)=10
2x+10-3x+15=10
x=15
ans:
Aaron is 15 years old
