4 (t + 3) = 20

Eliminate parentheses on the left side:

4t + 12 = 20

Subtract 12 from each side of the equation:

4t = 8

Now divide each side of the equation by 4,

and you have the solution.

==================================

Another way to approach it:

4 (t + 3) = 20

Divide each side of the equation by 4 :

t + 3 = 5

Now subtract 3 from each side,

and you have the solution.

This approach seems easier.

How do double elimination brackets work in tournament formats?

In a double elimination bracket, teams or players have to lose twice before they are eliminated from the tournament. Each match consists of two rounds: the winners' bracket and the losers' bracket. If a team loses in the winners' bracket, they move to the losers' bracket for a second chance. If they lose again in the losers' bracket, they are out of the tournament. This format allows for a fairer competition and gives teams a chance to recover from a single loss.
