Question

Answer 1

Dividing with negatives will result in a flip in the signs.

Explanation:

In the first equation, -7y>161, if you solve it, you will need to divide both sides by -7.

`-7y > 161\\ \\\\`

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:

y < -23

Notice the change in signs.

---------------------------

Now in the second equation, the constant (161) is negative. So if you solve this,

`7y > -161`

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:

y > -23

-----------------------

If you look at the signs in both answers, they are flipped.

Have a nice day!
