The sum of ali and mel's age is 39. if mel is 3 years younger than twice ali's age, how old is mel?

Age of Mel is 25 years.

Step-by-step explanation:

It is given that,the sum of Ali and Mel's age is 39. If Mel is 3 years younger than twice Ali's age.

Let 'x' be the Ali's age  and 'y' be the Mel's age

To find the value of x and y

sum of Ali and Mel's age is 39

⇒ x + y = 39    (1)

  Mel is 3 years younger than twice Ali's age

⇒ y = 2x - 3   (2)

⇒  2x - y = 3  (3)

(1) + (3) ⇒  

 x + y = 39

2x - y = 3

3x   = 42

x = 42/3 = 14

y = 2x - 3 = 14*2 - 3  = 25

Therefore the age of Ali = 14

Age of Mel = 25

94x=22572     /94

x=240.128
