Given:
Teddy has two sisters. One of them is 3 years younger than Teddy, the other one is 7 years younger than her only brother.
To find:
The age of older sister at the time when the younger sister was born.
Solution:

One sister is 3 years younger than Teddy.
Age of one sister = x-3 years

Therefore, the age of older sister is 4 years when the younger sister was born.
