The expressions for the ages of Jhonny, Freddy, Estefania and the total sum written in terms of a are :
- Jhonny = a
- Freddy = 3 + 2a
- Estefania = 2 + 3a
- Total ages = 6a + 5
Johnny's age = a
Freddy's age is 3 years more than 2 times Johnny's age ; hence, Freddy's age = 3 + 2a
Estefania's age is 2 years more than 3 times Johnny's age ;
Hence, Estefania's age = 2 + 3a
The ages of Jhonny, Freddy and Estefania's ages can be written using the addition operator thus :
a + (3 + 2a) + (2 + 3a)
a + 3 + 2a + 2 + 3a
a + 2a + 3a + 3 + 2
6a + 5
Therefore, the ages of Jhonny, Freddy, Estefania and the total sum of their ages are a, 3+2a, 2+3a, 6a+5 respectively.
