What property is 8y - 16 4(2y - 4)?

The expression ( 8y - 16 ) can be factored using the distributive property, which yields ( 8(y - 2) ). The expression ( 4(2y - 4) ) can also be simplified to ( 8(y - 2) ) by distributing the 4. Therefore, both expressions are equivalent, demonstrating that ( 8y - 16 ) is equal to ( 4(2y - 4) ).
