The property that justifies going from step 3 to step 4 is the **Addition Property of Equality**. This property states that if you add the same quantity to both sides of an equation, the two sides remain equal. In this case, adding 6 to both sides of the equation (5x - 6 = 19) allows the equation to maintain its equality while isolating the term with \( x \).
