In this problem, the algebraic expression (6x + 3) - 5x is simplified step by step, and each step involves the application of algebraic properties.

The multiplicative identity property states that multiplying any number by 1 does not change its value (i.e., $a \times 1 = a$). However, this property does not directly apply to the given expression.

Let's first break down the expression to identify which property the multiplicative identity might apply to. The given expression (6x + 3) - 5x involves combining like terms (terms with the variable $x$).

1. Step 1: (6x + 3) - 5x

   • This is the original expression, and no changes have been made yet.

2. Step 2: (6x - 5x) + 3

   • This step applies the commutative property of addition, which allows you to rearrange terms.

3. Step 3: x + 3

   • This step applies the simplification of like terms, specifically combining the terms $6x$ and $-5x$.

Thus, the multiplicative identity does not appear to apply directly to this expression. It would typically be seen when a factor of 1 is involved in multiplication, but no such operation is present in the given steps.
