Answer:

Teena is 14.5 years old and her brother is 17.5 years old.

Step-by-step explanation:

Let her brother's agebe the base unit (1 unit)

Therefore, Teena's age will be 1u - 3

Total age: 1u + 1u - 3 = 2u - 3

2u - 3 = 32

2u = 35

1u = 17.5

Her brother is 17.5 years old, and Teena is 17.5 - 3 = 14.5 years old.
