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:
The sum of both their ages is 41, so let's combine the variables h and t together.
We said that h = t - 13, so substitute this value into the equation.
Combine like terms.
Add 13 to both sides of the equation.
Divide both sides of the equation by 2.
Thomas's age is 27 years old.
