You can put this solution on YOUR website! 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
