Gina, Sam, and Robby all chose movies they would like to see over the next year. They each chose some dramas, comedies, and documentaries. Gina chose 11 movies total. Sam chose twice as many dramas, three times as many comedies, and twice as many documentaries as Gina. He chose 27 movies total. Robby chose 19 movies total with the same number of dramas, twice as many comedies, and twice as many documentaries as Gina. Which system of equations represents their movie choices?

x + y + z = 11

2x + 2y + 3z = 27

x + 2y + 2z = 19

x + y + z = 11

2x + 3y + 2z = 27

x + 2y + 2z = 19

x + y + z = 11

2x + 3y + 2z = 27

2x + 3y + 3z = 19

x + y + z = 11

3x + 2y + 2z = 27

x + 2y + 2z = 19
