Question

GPT-4o mini · Answer

Let's identify the justification for each step based on the transformation of the expressions:

Line 1 to Line 2:

Justification: Commutative Property of Addition
Explanation: The Commutative Property of Addition states that you can add numbers in any order. Here, \(9 + 8x\) is rearranged to \(8x + 9\).

Line 2 to Line 3:

Justification: Distributive Property
Explanation: When multiplying by \(1\) (as in \(1(8x+9)\)), you are effectively distributing \(1\) across the terms inside the parentheses, which simplifies to just \(8x + 9\).

So, to summarize:

Line 1 to Line 2: Commutative Property of Addition
Line 2 to Line 3: Distributive Property
