Answer:
3. -21 4. 16
Step-by-step explanation:
First we are looking for what number divided by 3 equals -7.
21 divided by 3 equals 7
So we know that we need the opposite of 21 which is -21.
Insert into equation:
-21/3=-7
So this makes the equation true.
Hence, the correct answer is -21.
Now we are looking for what number divided by -4 equals -4.
-16 divided by -4 equals 4.
So we know that we need the opposite of -16 which is 16
Insert into equation:
16/-4=-4
This makes the equation true.
Hence, the correct answer is 16
