## Algebra 1: Common Core (15th Edition)

$3(3x-1)-3(5x-3)=4$ $9x-3-15x+9=4$ There is no division or subtraction so the first two choices are incorrect. If you used the commutative property with parentheses, then the parentheses will be there after. Therefore, it must be the distributive property, because the coefficient is distributed to the items inside the parentheses by multiplication.
