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
