What would be the best first step to solving the equation?

3 = x + 5

• add 3 to both sides

• subtract 5 from both sides

• add 5 to both sides

• subtract -5 from both sides

What would be the best first step to solving the equation?

-18 = m + 12

• add 18 to both sides

• subtract 18 from both sides

• add 12 to both sides

• subtract 12 from both sides
