Hi
a number is additive inverse if the sum =0
so 0 as the additive inverse of 12 would be -12.
and the additive inverse of -12 is 12 (it works both ways)
Answer:
The sum is 24
Step-by-step explanation:
The additive inverse of a number is its opposite, that is, it is that number that when added with itself, using an opposite sign, yields a result equivalent to zero.
x = 12
x + y = 0
12 + y = 0
y = -12
additive inverse is -12
12 - (-12)
12 + 12
24
