Don't Understand Quiz Answer

Question

This question appeared in the quiz. I paid points to unlock the answer and it displayed "3". I didn't understand why and tried to get a hint to help me but it didn't give me a hint and deducted one of my points. I repeated the hint request thinking maybe I clicked the wrong button and same result (and another point lost!) Meh! Why is the answer 3 here? if x=15, wouldn't the code output x (i.e., 15) per the WriteLine statement? And if modulus is at play, how could 3 be the answer? 15 % = 6 can't even be solved because 6 can't be the remainder with 15 being the starting point. Is the answer right in front of my face? And how do I get my 2 points back since I never got the hints? Thanks!

What is the output of this code?
int x = 15;
int y = 6;
x %= y;
Console.WriteLine(x);

Answer 1

x %= y is the same as x = x % y

Answer 2

Lisa really it is easier than you think as the % is asking for the remainder 6 goes into 15 twice leaving the remainder of 3 ...
hope that helps.
Thanks

Answer 3

% operator return reminder.
x%=y
x=x%y=15%6=3
Since 15/6=2
/ return quotient.
