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 174 points. School B started with 90. 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.
Which equation models the scoring in the final round and the outcome of the contest?
9x+6x−174=−9x+90
9x−6x−174=9x+90
9x−6x+174=9x+90
6x−9x+174=9x+90
x=
