James is a years old. His sister is four years younger than him. His mother is 28 years older than his sister. If the mother is y, which formula describes the relationshio between James and his mother's age?

Answer 1

M = a + 24, where a is James' age and M is his mother's

Explanation:

a = James' age

His sister is 4 years younger than him:

a - 4 represents his sister's age.

His mother is 28 years older than his sister:

(a - 4) + 28

or a + 24 represents his mother's age

Let M = his mother's age

M = a + 24
