Team one had 4 times less people than team two. After 6 people quit team two and 12 people were transferred from team two to team one, both teams became equal. How many people were there in team one?

There was 10 people on team one. I just did process of elimination by going through numbers and trying them out. It would be 10 on team one and 40 on team 2. Take 6 off 40 to get 34 then switch 12 making both have 22.
