Question

X + y = y + x
a. True
b. False

Answer 1

The correct answer is : A. True

Answer 2

This is indeed a true equation.

We can see there is one x and one y on the left side of the equals sign and a matching set of x and y on the right side as well. This is known as the commutative property of addition in which changing the order of the variables does not change the result.
