Answer:
33 years
Explanation:
Let's solve it using mathematical assumptions.
First, let's assume THOMAS age to be x
Therefore, Huilan's age would be (x-7)
The sum of their ages would be:
x + (x - 7).
From the question, the sum of their ages equals 59.
The expression becomes:
x + (x - 7) = 59
x + x - 7 = 59
2x - 7 = 59
2x = 59 + 7
2x = 66
x = 66/2
x = 33.
It means that, THOMAS'S AGE is 33 years.
Huilan's age will then be 33-7 = 26years
