Step-by-step explanation:

Let's set Huilan's age to h and Thomas's age to t.

Since Huilan is 13 years younger than Thomas, we can write:

• h = t - 13

The sum of both their ages is 41, so let's combine the variables h and t together.

• h + t = 41

We said that h = t - 13, so substitute this value into the equation.

• (t - 13) + t = 41

Combine like terms.

• 2t - 13 = 41

Add 13 to both sides of the equation.

• 2t = 54

Divide both sides of the equation by 2.

• t = 27

Thomas's age is 27 years old.
