Explain what opposites are and give examples of real world situations

Opposites in the numbers world refer to numbers that have the same absolute value, but one is negative, while the other is positive.

For a real world example, consider if you have your friend 5 dollars. The amount you have in the transaction is the opposite of the amount he has in the transaction.

a² + b²= c²

24² + 7² = c²

c= 25

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
