To solve the equation
x + 5 = 8
 I would ....

• subtract 5 from x
• subtract 5 from both sides
• subtract 5 from one side and add 5 to the other
• add 5 to both sides

in 3a =12,
I would....

• add 3 to both sides
• subtract 3 from both sides
• divide both sides by 3
• divide just the right by 3

What is the inverse operation that must be done to both sides of the equation?
x - 17 = 17

• subtract 17 from both sides
• multiply both sides by 17
• add 17 to both sides
• divide both sides by 17
