Final answer:
The concept of additive inverses can be used to find equivalent expressions by replacing a term with its additive inverse.
Step-by-step explanation:
The concept of additive inverses can be used to find equivalent expressions. An additive inverse of a number is the number that, when added to the original number, gives a sum of zero. For example, the additive inverse of 5 is -5 because 5 + (-5) = 0.
Using additive inverses, you can rewrite an expression by replacing a term with its additive inverse. For example, if you have the expression 3x + 2, you can replace 2 with its additive inverse (-2) to get 3x - 2.
By rearranging the terms using additive inverses, you can find equivalent expressions that have the same value but may be written differently.
