Answer:
Step-by-step explanation:
Let Emma's age be 2x years, then:
Elsa's age is x years, also:
Bella's age is x - 2 years.
In one years time the sum of their ages
= 2x + 1 + x + 1 + x - 2 + 1
= 4x + 1 where x = Elsa's age now.
5 years before now
Sum of their ages
= 2x -5 + x - 5 + x - 2 - 5
= 4x - 17 where x = Elsa's age now,
The answer is square root of 2
