Question

Find the inverse with respect to addition of 9​

Answer 1

-9.

Explanation:

Because 9 + (-9) = 0.

Answer 2

Answer: -9

Work Shown:

Let x be the additive inverse of 9

This means it adds to 9 to get 0

x+9 = 0 which solves to x = -9 after subtracting 9 from both sides.

So -9+9 = 0 and 9+(-9) = 0.
