Step-by-step explanation:
age of alia's first brother= x
age of alia's second brother=x ( as both are twin)
age of alia = x+9
mean of three children = sum of their age/ no. of children
= x+x+x+9/3
=3x+9/3
=x+3

Answer:
the age of twin brother is x
the age of alia is (x + 9)
mean age of 3 children = [x + x + ( x + 9 )]/3.
= ( 3x + 9 )/3
= (x + 3) years
