Best ResponseYou've already chosen the best response.3So you're saying there exist the integers x, and y, where if you multiply by a and b, you end up with another integer.

Best ResponseYou've already chosen the best response.0So that means there exist integers x and y such that ax+by=d is also an integer. Am I right?@wio

Best ResponseYou've already chosen the best response.3I would translate that expression to say: "There exists two integers, \(x\) and \(y\), such that \(ax+by\) is an integer.

Best ResponseYou've already chosen the best response.3@ajprincess Yeah. I think the \(d\) is just there for the sake of saying the result is an integer.
