Let x equal Thomas' age.  Then Huilan's age is 2x.  Set up an equation to model this situation:

x+2x=78

*Combine like terms*

3x=78

*Divide both sides by 3*

x=26


Hope this helps!!

Since the sum of both Thomas and Huilan’s age is 78—

You would have to divide by 3, because, the problem you are trying to solve is asking you for 1/3 of the ages.

(Huilan = 2/3)
(Thomas = 1/3)

So, you divide 78 by 3 and you get 26.

Thomas = 26
