Answer:
y = 3, 4, or 5
Step-by-step explanation:

<u>Step 1; Simplify the Double Inequality</u>
Let's first simplify this double inequality to make answering this problem a bit easier. This means getting the middle term to be just y, without any added constant or coefficients.
In this case, this is a fairly simple process, as all we have to do to get y by itself is just divide the <em>entire inequality</em> by 2. This means that we will also divide the 5 and 12 by 2. (Note that the signs stay the same because we are not dividing by a negative number.)
Doing so gives us the following double inequality: 2.5 < y < 6.
<u>Step 2: Identify the Integers in this Range</u>
Now that we have a simplified double inequality, all we need to do is find all of the integers in its range. (Recall that an integer is <u>any number that is not a fraction when fully simplified (ex. …-1, 0, 1...)</u>.)
In other words, we need to find all of the integers <em>in between</em> 2.5 and 6. Note that we don't include 6 because of the "<" sign, which indicates that the 2.5 and 6 are not included in the set. These numbers are 3, 4, and 5, making them your answer. Hope this helps!
I don't think this is possible.
The factors of -9 are:
-1 x 9
-9 x 1
-3 x 3
And when you add them together you get:
-1 + 9 = 8
-9 + 1 = -8
-3 + 3 = 0
Sorry but there is not an answer. :(
