John is x years old and his mother is 25 years older than he is.

a) How old is John's mother?

My answer: x + 25 = mother

There's nothing wrong with this part.

b) What is the sum of their ages now?

my answer: x + mother = current age

I would suggest something different for this answer. Note that John's age is x and his mother's age is x+25. What do you get when you add them together?

c) when john is 12 years old, how old is his mother?

my answer: 12 + 25 = 37.

I see nothing wrong with this part either, given the information you've provided in the problem.

I hope this helps!

2x + 25

Chris, thank you.
