Let = Annie's age now
Just look at the part that says
"when Alma was as old as Annie is now"
That means that Alma was years old
The difference in their age will always be
That means that when Alma was years old,
Annie was
It says that Alma is now twice that age, so

Alma is twice that age, or 2x18 - 36
OK
