Question

Problem solving: Leann is two years younger than Rachel Rose is the same age as Luann if you add all their ages together, the sum is 29. How old is Luann?​

Answer 1

Luann is 9 years old.

Explanation:

Let,

x = Luann's age

y = Rachel

z = Rose

According to given statement;

x = y - 2

x = z

x + y + z = 29

Putting values

(y-2) + y + (y-2) = 29 (as z = x and x = y-2)

y -2 + y + y -2 = 29

3y - 4 = 29

3y = 29 + 4

3y = 33

Dividing both sides by 3

y = 11

Luann's age = 11 - 2 = 9 years

Thus,

Luann is 9 years old.
