Question

a girl is 5 years younger than her brother if the sum of their ages is 23 years find the ages of the girl and her brother with full solutions​

Answer 1

this is the correct answer

Answer 2

Answer:

let 'x' be the age of her brother

so the age of girl is ( x- 5 )

Step-by-step explanation:

x+(x - 5) = 23

x + x - 5 = 23

2x - 5 = 23

2x = 23 + 5

2x = 28

x = 28/2

x = 14

The age of her brother is 14 years

and the age of the girl is = ( x - 5)

= ( 14 - 5)

= 9 years
