The ages of three siblings combined is 27. The oldest is twice the age of the youngest. The middle child is 3 years older than the youngest. Write and solve an equation to find the ages of each sibling.

Answer 1

y = youngest , m = middle , e = eldest

y + m + e = 27

e = 2 y

m = y + 3

substituting ... y + y + 3 + 2 y = 27
