Takeshi claims that the solution to the equation 5x - 3(2x - 4) = 7x + 16 is x = -0.5. He shows the steps below to justify his solution.

Given: 5x - 3(2x - 4) = 7x + 16
Step 1: 5x - 6x + 12 = 7x + 16
Step 2: -x + 12 = 7x + 16
Step 3: -8x + 12 = 16
Step 4: -8x = 4
Step 5: x = -0.5

Select the two correct justification for the given steps.
Step 1: Associative Property
Step 2: combining like terms
Step 3: combining like terms
Step 4: Reflexive Property of Equality
Step 5: Division Property of Equality
