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.

Which of the following has an equals sign?

• Equation

• Expression

How do we solve f - 12 = -4

• add -12 to both sides

• subtract 12 from both sides

• add 12 to both sides

• add 4 to both sides
