Hey there!
To find the opposite of a number, you switch its sign, and to do so, you would multiply by -1. This gives us the equation below.
n=-n+96
To find our number, we need to isolate all of our n's on one side of the equation. Let's try adding n to both sides.
2n=96
We divide both sides by 2.
n=48
As you can see, the opposite of 48 is -48, and 48 is 96 more than -48.
Therefore, our number is 48.
I hope this helps!

umm...thanks for the points lol
Answer:
y = {1,2}
Step-by-step explanation:
5y^2 - 4y - 9 = y + 1
5y^2 - 5y - 10 = 0
5(y^2 - y - 2) = 0
5 (y - 2) (y - 1) = 0
y = {1,2}
