Hello,
We should start with: What does "Undefined" mean?
It means a number cannot be divided by zero.
So the only answer for this is y = 6
To better understand why you can't divide by zero, let's set up a real example.
If there no candy and 6 kids. How many pieces of candy will the kids get?
Right. Nothing. It would look like this 0 candy divided by 6 kids.
Now, let's suppose there is 6 pieces of candy but no kids.
How many pieces of candy will no kids get? See it doesn't make sense, that's why it's called undefined.
