Solution

## The correct option is A 3−2x3x+5The additive inverse of a number is what you add to a number so that the sum will be zero. In other words, the additive inverse of x is another integer y, as long as the sum of x+y=0. For example, the additive inverse of 5 is −5 because their sum 5+(−5)=0.Similarly, the additive inverse of the fraction 2x−33x+5 is −(2x−33x+5) or 3−2x3x+5 and their sum is determined as: 2x−33x+5+(−3+2x3x+5)=2x−3−3+2x3x+5=03x+5=0Hence, the additive inverse of 2x−33x+5 is 3−2x3x+5
