Answer 1

Answer:

14

Step-by-step explanation:

given : Alisha's age = n

and , her brother's age = 7

Now , after 2 years

Alisha's age = 2n

her brother's age = 7+2

now the equation formed by the all the above discussion is

Alisha's age+ her brother's age = 39 (given in the question )

2n+7+2= 39

2n+9= 39

2n= 39-9

2n= 30

n = 30/2

n= 14
