Step-by-step explanation:
If -16 is being divide by p, you will have to multiply it by -4, which you can't do because you can't multiply a variable by a whole number so you have to make it like this, -4p, which is the same as saying -4 is being multiplied by p. Then you switch sides. by this I mean to switch where your numbers are, your numbers were like this, -16=-4p so now you have to make it into this, -4p=-16, so you can simplify it. Because the variable p is being multiplied by 4, we have to get rid of the variable so we have to divide -4 by -16 which is 4. it is not a negative because negative divided by negative is positive.
4 is your final answer. explanation is above. :)
