Answer:
Cowboys - 19 points
Giants - 29 points
Packers - 43 points
Explanation:
We can set up an algebraic equation. Let the variable x be the Cowboys' points. From there, the Giants have 2x - 9 points, and the Packers have
2x + 5 points (add 14 to Giants' total). Adding it all up and equating it to 81, we have 5x - 4 = 81. Add 4 to both sides, and divide by 5 to find that the Cowboys scored 19 points. Plug in 19 as x for the other two teams, and the Giants scored 29 points and the Packers scored 43 points. (Somehow without Aaron Rodgers.)
