Harry is twice as old as Doyle. Doyle's age is x years. Write in terms of x. A. Harry's age is 5 years ago. B. Doyle's age is 5 years ago. C. Find Doyle's age now if Harry's age was three times Doyle's age five years ago.

Mathematicsplease help quick!! 
Damon,
Doyle = x
Harry = 2x
Harry five years ago = 2x5
Doyle five years ago = x5
2x5 = 3(x5) = 3 x  15
x = 10
