Question

Huilan is 10 years older than Thomas. The sum of their ages is 102. What is Thomas's age?

Answer 1

The is easy since adding both ages is 102 the means 102- 10 =92 hope it helps

Answer 2

Thomas age = X
Huilan age = X + 10
Sum of both ages = 102.

How old is Thomas?

X + X + 10 = 102
2x + 10 = 102
2x = 102 - 10
2x = 92
X = 92/2
X = 46.

Thomas is 46 years old.
