Coach Johnson knows that this system of equations represents the number of tickets sold before the tournament, x, and at the door, y. x + y = 743
x – y = 75
An assistant told him that 409 tickets were sold at the door and 334 tickets were sold before the tournament. Is this solution correct? Explain.

What can each term of the equation be multiplied by to eliminate the fractions before solving? x – + 2x = + x 2 6 10 12

Which equation represents the function on the graph?
