# Which expression must be added to #3x-7# to equal 0?

Additive inverses are terms or numbers that add up to zero (adding opposites).

This indicates an identical number, but with a positive and a negative.

Here are a few instances of additive inverses.

Even if you were unaware of it, this is a very helpful idea that is utilized when solving equations (this is how one term is "moved to the other side").
