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.

• 12(-6+2x-3y)

• 12(6-2x+4y)

• 9(-8+15x-4y)
