It's definitely transitive property, like the one (briant1234) above said. If quantities are equal to the same quantity, they are equal to each other. In other word:
If a=b and a=c, then b=c.
In this case 2x+4 and 3x-6 are equal to y, so they are equal to each other too. It does makes sense, right?
P.S. Substitution means replacing quantity by another quantity.
Replacing y to 2x+4, so:
y = 3x-6
(2x+4) = 3x-6
Substitution property still give the same result, but transitive property is more common and formal. So I rather do transitive than substitution.

It could be either Substitution or Transitive Property.
It could also be the axiom that states that "things equal to the same thing are equal to each other".
