Answer:
The property used here is:
Commutative property of addition
Step-by-step explanation:
Commutative property of addition states that if a and b are any two elements
then, a + b = b + a
We are given a equality we have to determine the property used here
5x · (4y + 3x) = 5x · (3x + 4y)
In the above equation, 4y + 3x = 3x + 4y
a= 4y and b= 3x
Then, a+b=b+a
Hence, the property used above is:
Commutative property of addition
