Answer:
Step-by-step explanation:
We can subtract a term from another if they have the same variable. Both and
have the variable
, so we can subtract them.
When subtracting these terms, we subtract the coefficients and keep the variable.
So:

The commutative property of addition means the order of the addends doesn't matter; we get the same sum. In symbols
<span>11 + 7 = 7 + 11, choice B, is a good illustration of commutativity.
The next part asks us to use the commutative property. Looking at the choices, we see it's not the commutative property of addition we're to use, it's the commutative property of multiplication. Let's write that generally first:
</span>
Applying that, <span>(4 + 7) * 3 = 3*(4+7), again choice B.
</span>
