Final answer:
The System.out.println command in question will display "x = " without the value of x or y as they are not included in the output command.
Step-by-step explanation:
Assuming that x = 2 and y = 3, the statement System.out.println("x = "); will only display "x = " because it does not include the value of x after the equals sign. The actual value of x (which is 2) or y (which is 3) is not printed because they are not included in the system out command.
