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?

Luann is 9 years old.

Step-by-step 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.

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
