Answer 1

Answer:

Boy's age is 7 years and girls age is 19 years

Step-by-step explanation:

Let the boy age be x and girl age be y

x+y=26... equation 1

4(x-3)=y-3

4x-y=9....equation 2

On adding equation 1 and 2 we get

5x=35

x=7

y=19

The boy's age is x=7 years and girl's age is y=19 years.
