An inverse operation is

• reversing the sign in an inequality
• using the opposite operation to solve equations
•  A number’s distance from zero

Like terms are 

• numbers or same variable raised to the same power
• equal numbers
• only unknown values

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.

Choose the first step in solving the following equation.
-3y - 12 = 14

• add 3 from both sides
• add 12 to both sides
• subtract 12 from both sides
