Question 699606: Adam is x years old. His brother Tom is twice as old as him. His sister Suzanne is 5 years older than him. His mum is the same age as Tome and Suzanne added together.
Write, in terms of x, the ages of Tom, Suzanne and the mother.
Answer by Simnepi(216)   (Show Source):
You can put this solution on YOUR website! Let's start working out the age of each person, starting with Tom.
Since Adam is x years old and Tom is twice that i.e. 2 times Adam's age, so we can say
Tom is 2x years old.
Now, Suzanne is 5 years older than him, (Tom i assume), so we add 5 to Tom's age. This means that
Suzanne is 2x+5 years old.
Now, Adam's mother is Tom and Suzanne's ages added together, that is
2x + (2x+5)
This gives Adam's mother's age as
4x+5
Hope this helps!
