Answer 1

• Equation is 74 + 18 = x

• Number of teams that started competition = 92 teams

Step-by-step explanation:

74 teams have been eliminated and 18 teams remain.

Assume the number of people who started the competition is x:

Number of teams eliminated + Number of teams remaining = Number of teams that started competition

74 + 18 = x

Solving that equation:

74 + 18 = x

x = 92 teams
