Answer 1

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.
