How do you solve formula if 12 teams in single eliminition?

In a single-elimination tournament with 12 teams, you'll need to determine how many matches are required to declare a winner. First, recognize that each match eliminates one team. Since there are 12 teams, you'll need to eliminate 11 teams to find the champion, which means you will have 11 matches in total. To organize the initial rounds, you can have 4 matches in the first round (8 teams), with 4 teams getting a bye, leading to subsequent rounds until a winner is determined.
