One difference between equations and expressions would be...

• you solve both of them using inverse operations.

• you flip the symbol when you multiply or divide by a negative

• equations have an equals because they show two equal expressions. Expresions have terms and operations.

6n + 2(3 - 5n)

• n + 6

• 6 - 4n

• 16n + 6
