Answer:
Dividing with negatives will result in a flip in the signs.
Step-by-step explanation:
In the first equation, -7y>161, if you solve it, you will need to divide both sides by -7.
Since you are involving a negative, you will have to switch the signs. That means that if you have solved this, the answer would be:
<h3>y < -23</h3>
Notice the change in signs.
---------------------------
Now in the second equation, the constant (161) is negative. So if you solve this,
You will only need to divide both sides by 7, which is a positive number. That leaves the sign to stay the same, so the answer would be:
<h3>y > -23</h3><h3>-----------------------</h3><h3>If you look at the signs in both answers, they are flipped.</h3><h3 /><h3 /><h2>Have a nice day!</h2>
