Given data:

The age of George in terms of Anthony age is G=A+4.

The given age of Anthony in terms of sylvia is A=S+3.

The combined age is A+G+S=234.

The age of George in terms of Sylvia is,

G=(S+3)+4

=S+7

Substitute the above value and given value in the combined age.

S+3+S+7+S=234

3S+10=234

3S=224

S=224/3

George age is

7+224/3=245/3

Anthony age is,

A=3+224/3

=233/3

Thus, the age of George is 245/3, Anthony is 233/3, and Sylvia is 224/3.
