\begin{tabular}{l} One of the steps Neesha used to correctly solve an equation is shown below: \\ Line \( 1: 18+8 x-4=13 \) \\ Line \( 2: 8 x+18-4=13 \) \\ Which set of statements describes the procedure Neesha used to go from line 1 \\ to line 2 and identifies the property that justifies that procedure? \\ O Neesha changed the order of the 18 and \( 8 x \). \\ This procedure is justified by the associative property of addition. \\ O Neesha changed the order of the 18 and \( 8 x \). \\ This procedure is justified by the commutative property of addition. \\ O Neesha added -18 to both sides of the equation. \\ This procedure is justified by the additive inverse property. \\ \hline O Neesha added -18 to both sides of the equation. \\ This procedure is justified by the additive inverse property of equality. \end{tabular}

When Neesha moved from line 1 to line 2, she didn’t fundamentally change the equation; she simply rearranged the terms on one side. By shifting 18 ahead of \(8x\), she showcased the flexibility of how we can present addition. This impressive move is totally backed by the commutative property of addition, which states that numbers can be added in any order without changing the sum! Now, let’s talk about the math magic Neesha worked with those equations! While it may seem like swapping numbers is just a neat trick, it’s essential to remember that if you were actually adding or subtracting to “solve” an equation, you need to ensure that both sides remain balanced. Mistaking this will certainly lead to some head-scratching results. So always double-check that you’re following the rules of equality when you’re making those switches!
