Amelia Bauer · Answer 1

So if she had 23 now I would say she started with 24:

So 23-11=12 so this was half of the stamps before buying the 11 extra

but 12x2=24 which would have been to total sum of stamps she started with.

Owens · Answer 2

X/2 + 11 = 23

x/2 = 12

x = 24

She started with 24 stamps.
