Seven years ago, Grogg's dad was 9 times as old as Grogg, and 6 years ago, his dad was 3 times as old as Grogg. How old is Grogg's dad currently?

D==Dad,     G==Grogg

 

[D - 7] == 9 * [G - 7]......................(1)

[D - 6] == 3 * [G - 6].....................(2), solve for D, G

 

D ==10 years ??!

G ==22 / 3     ??!

 

P.S. Your question doesn't make sense as written. Check your numbers carefully.
