Yoga fun charges $63 starting war plus $12 per class. Yoga for all charges no starting fee and $15 per class. For how many classes will the cost be the sameat both places plz explain

Yoga fun: 63 + 12n
Yoga: 15n
when is 15n = 63 + 12n
15n  12n = 63
3n=63
n = 21
21 classes would cost the same for either club
