broadcasting of Equal ? (newbie question)

I noticed that e.g.
Solve[{x + y - 1, 2 x + y - 2} == {0, 0}, {x, y}]
can be written as
Solve[{x + y - 1, 2 x + y - 2} == 0, {x, y}]
but I cannot find the rule that allows this.
(E.g., I do not find it in the help for Equal
or the help for Solve.)

Can you point me to it?

Thanks,
Alan
