In 10 years, Roman will be 2 times Seth's age. 5 years ago Roman was 3 times Seth's age. HOW OLD IS SETH???

aalyn [17]

Let s be Seth's age. let r be Romans age. 5 years ago Seth was s-5 and Roman was three times as old, or 3(s-5), or 3s-15=r-5

in ten years Seth will be s+10 and Roman will be twice as old, or 2(s+10), or 2s+20=r+10
3s-15 =r-5
r=3s-10

2s+20=r+10
r=2s+10

3s-10=2s+10
s=20

Seth is 20 years old

setting the two equations equal gives us
3(s-5)=2(s+10)
3s-15=2s+20
s=35
