Question

Huilan is 5 years older than Thomas. The sum of their ages is 49. What is Thomas's age?

Answer 1

Thomas is 22 years old.

Explanation:

h = t + 5

h + t = 49

To find Thomas's age:

(t + 5) + t = 49

2t + 5 = 49

2t = 44

t = 22

Therefore, Thomas is 22 years old.

Answer 2

22

Explanation:

H = T + 5

H + T = 49

Substitute the first equation into the second

(T + 5) + T = 49

2T + 5 = 49

2T = 44

T = 22
