Explain why the additive inverse of -3 + x is 3 - x.
The additive inverse of -3 + x -(-3 + x) 3 - x
Because (-3 + x) + (3 - x) -3 + 3 + x - x and each pair cancels to become 0.
since (-3+x) + (3-x) 0, -3+x and 3-x are each other's additive inverses u is the additive inverse of v if and only if u + v 0
