What are two expressions that are equivalent to

-2 (4-y) ?

First we need to answer the expression, we will say the y is negative. 4x-2=-8, but it will be multiplied by the - y. Knowing this, multiplying 2 negative makes the answer positive, so the final answer would be 8y (8 times y). So 2 other expression to show this would be - 8x - y (-8 times - y) and another would be 16/2 (16 divided by 2)
