Question

A girl is 6 years younger than her friend.If the sum of their ages is 34 years,find the age of the girl.​

Answer 1

Answer:

By subtracting 34-6 to find the girl's age.

so answer is 28.

Answer 2

Let the age of girl be x

then age of her friend = x + 6

Sym of their age = 34

x + (x + 6) = 34

x + x + 6 = 34

2x + 6 = 34

2x = 34 - 6

2x = 28

x = 28/2

x = 14

Girl's age = 14 years

Her friend's age = 14 + 6 = 20 years
