Three siblings are comparing their ages. Jenna is the youngest. Her brother Carl is 6 years older than her. Her sister Eve it twice her age. The sum of their ages is 42. Let j represent Jenna's age.

jenna age = 9

carl age = 15

eve age = 18

Step-by-step explanation:

let, jenna age = j then,

carl age=6 + j & eve age= 2j

By the question,

j + (6+j) + 2j =42

or, 4j + 6=42

or, 4j = 42-6

or, j = 36÷4

j = 9
