Suppose y is a positive integer. If x – (–y) = z, will z be greater than or less than x? Explain your answer. z is greater than x, since –(–y) is the same as subtracting y.

z is greater than x, since subtracting –y is the same as adding its additive inverse, y.

z is less than x, since subtracting –y is the same as subtracting its additive inverse, y.

z is less than x, since –(–y) is the same as adding –y.
