Call their ages (Edna, Ellie,and Elsa): n, n+1, and n+2. Those are consecutive integers.


The sum of those ages = 123.


n + n+1 + n+2 =123


Add the n's and the numbers.


3n + 3 = 123


Subtract 3 from both sides.


3n=120


Divide both sides by 3.


n=40.


Edna = n = 40


Ellie = n+1 = 41


Elsa = n+2 = 42
