A student solves the following equation:

Problem: 2(x−3)+3x=19

Step 1: 2x−6+3x=19

Step 2: (2x+3x)−6=19

Step 3: 5x−6=19

Step 4: 5x−6+6=19+6

Step 5: 5x=25

Step 6: x=5

What property justifies going from step 3 to step 4?

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 value to both sides of an equation, the equality is maintained. In this case, 6 is added to both sides of the equation from step 3 to step 4.
