Takeshi claims that the solution to the equation 2x - 2(4x - 3) = 6x + 12 is x = -0.5. He shows the steps below to justify his solution. Given: 2x - 2(4x - 3) = 6x + 12
Step 1: 2x - 8x + 6 = 6x + 12
Step 2: -6x + 6 = 6x + 12
Step 3: -12x + 6 = 12
Step 4: -12x = 6
Step 5: x = -0.5

Select 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
