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.
