Challenge Schools A and B are competing in an academic contest. Correct answers earn 9 points, Incorrect answers lose 6 points. In the final round, School A gives the same number of correct and
incorrect answers, School B gives no incorrect answers and the same number of correct answers as
School A. School A started the final round with 198 points, School B started with 72. The game ends
with the two schools tied. Let x represent the number of correct answers given by School A in the final
round. Write an equation that models the outcome of the contest. Then find the number of answers
that each school got correct in the final round,
