The commutative property is a mathematical property that states to combine like terms. Like terms are terms that have the same variables and powers.
In the given:
8x + 4 + 6x +2
By adding 8x and 6x, and 4 + 2, you are using the commutative property to simplify this expression.
8x+6x = 14x
4+2=6
The simplified equation is 14x + 6

If you would like to further simplify this expression, factor out the greatest common factor.
The further simplified expression would look like: 2(7x + 3)
