Which system of equations could be used to find the number of tickets sold before the tournament, x, and the number of tickets sold at the door, y? Remember, 743 tickets were sold, and 75 more tickets were purchased before the tournament than at the door. Select the correct system based on the scenario.
y = x + 75
y = 75x + 743
y = x + 75
y = x + 743
x + y = 743
x – y = 75
x + y = 743
y – x = 75
