25 + x = 13 + (25 + x) / 2 + 7
25 + x = 20 + (25 + x)/2
5 + x = (25 + x)/2
10 + 2x = 25 + x
x = 15

(Desmos confirms that algebra)

40/2 + 7 = 27, though, rather than 28, so let's see what happens if we do x = 15 - ε

(40-ε)/2 + 7 = 27 - ε/2. Note, 15 - ε years have elapsed, giving her the age of 27 - ε. We have that 27 - ε/2 > 27 - ε, though, so she's still too young.

I think that checks out? Weird how discrete it is, though
