Step-by-step explanation:
The commutative property for the addition states that when the order of two (or more) numbers is changed, the result of the addition does not change.
Mathematically, this means that:
![a+b=b+a](https://img.qammunity.org/2021/formulas/mathematics/high-school/j5ddbadg7l6dv4bxrucnj1u3n739yhqdn8.png)
where a, b are two numbers.
In this problem, we have the following addition:
![y+j](https://img.qammunity.org/2021/formulas/english/middle-school/q8219sk6pqousloxxmwvcegjwft7b29row.png)
By applying the commutative property, we can swap the order of the two variables y and j, and the result will remain the same. So we can write:
![y+j=j+y](https://img.qammunity.org/2021/formulas/english/middle-school/30mowziy1y2l7a4y8d5oczwx4vibby2jof.png)
