additive inverse is when in an equation there is a plus zero. you automatically know that anything plus 0 is still that number, so that is additive identity.
It depends on whether you mean additive inverse or multiplicative inverse.
It is 3w - 10
To find the additive inverse of any number, just change the plus sign (or no sign) to a minus sign, or (as in this case), if there already is a minus sign, change it to a plus sign (or no sign).
The additive inverse is a number subtracted it's self is 0: x + (-x) = 0 The additive identity is a number plus/minus 0 is itself: x +/- 0 = x They're very similar
