He is applying commutative property to solve the given problem.

<h2>Given that</h2>

Jakob is asking to simplify the expression -3a + 4b + 5a + (-7b).

He writes: -3a + 4b + 5a + (7b) = -3a + 5a + 4b + (7b).

We have to determine

Which property allows him to do this?

<h2>According to the question</h2>

Jakob is asking to simplify the expression -3a + 4b + 5a + (-7b).

<h3>The commutative property of addition can be used when adding more than two numbers as well and is often used in conjunction with the associative property of addition. </h3>

To solve the expression he is applying the commutative property of the addition.

Then,

The solution of the equation is,

$\rm -3a + 4b + 5a + (-7b)\\\\ -3a + 4b + 5a + (7b) \\\\\ 


$

Hence, he is applying commutative property to solve the given problem.
