Answer:
Step-by-step explanation:
Represent Anita's age by a and Basilo's by b.
Then a = b - 4.5, and 3(a + 6) = 36 (where I have "invented" the value 3).
Substituting b - 4.5 for a in 3a + 18 = 36: 3(b - 4.5) + 18 = 36
Performing the indicated multiplication:
3b - 13.5 + 18 = 36, or
3b + 13.5 = 18, or
b = 18 - 13.5 = 4.5
Basilo is 4.5 years old, whereas Anita is 9 years old.
