Use the Commutative Property to determine the missing step in proving the equivalence of 12a+10+a=10+a+12a.

Step 1: [missing]

Step 2: 10+13a=10+13a

Step 3: The expressions are equivalent because they both equal the same value.

12a+10+a−a=10+a+12a−a
d plus 10 plus a equals 10 plus a plus d

10+12a+a=10+13a
d plus 10 plus a equals 10 plus a plus d

12a+10+a−10=10+a+12a−10
d plus 10 plus a equals 10 plus a plus d

12a+10=10+12a

To determine the missing step using the Commutative Property, we need to rearrange the terms in the expression \(12a + 10 + a\).

The missing step is:

**Step 1:** \(10 + 12a + a = 10 + a + 12a\)

So the correct response is:

**10 + 12a + a = 10 + a + 12a**

This step uses the Commutative Property to arrange the terms in a new order.
