Question

Select the property that justifies that action.

Answer 1

Answer:

F. Action: Add 4 to both sides.

B. Property: Addition Property of Equality

Step-by-step explanation:

You would add four to both sides of the equation, thus making x = 20.

x - 4 =  16

  +4 = +4

   x  = 20

(Edit) The property would be the Addition Property of Equality.
