Question

question when solving an equation, isaac’s first step is shown below. which property justifies isaac’s first step? original equation: 2+(4 + x)=3 first step: (2 + 4)+x=3 answer multiplication property of equality division property of equality associative property of multiplication associative property of addition

Explanation:

The associative property of addition states that for any real numbers \(a\), \(b\), and \(c\), \((a + b)+c=a+(b + c)\). In the given equation, the grouping of the addition operation has changed from \(2+(4 + x)\) to \((2 + 4)+x\), which is an example of the associative property of addition.

Answer:
