Apair of numbers whose sum is zero?

1 and negative 1. Any number plus the opposite (negative) version of itself works. Hope this helped, could I possibly get brainliest?

i think it may be Origin

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
