Answer:
y = -3
Step-by-step explanation:
-8 = 2y - 2
-8 + 2 = 2y - 2 + 2 → -6 = 2y
-6 ÷ 2 = 2y ÷ 2 → -3 = y
y = -3

Answer:
![x\leq 9](https://tex.z-dn.net/?f=x%5Cleq%209)
Step-by-step explanation:
Subtract 7 From both sides
![x+7-7\le \:16-7](https://tex.z-dn.net/?f=x%2B7-7%5Cle%20%5C%3A16-7)
7-7 = 0, 16 - 7=9
That leaves ![x \leq 9](https://tex.z-dn.net/?f=x%20%5Cleq%20%209)
Hope this helps

Answer:
176 books
Step-by-step explanation:
Let's call the number of fiction books 'F', and the number of non-fiction books 'N'. Then, we can write the following system of equations:
eq1:
![F = 3N](https://tex.z-dn.net/?f=F%20%3D%203N)
eq2:
![2*(F - 122) = (N - 24)](https://tex.z-dn.net/?f=2%2A%28F%20-%20122%29%20%3D%20%28N%20-%2024%29)
![2F - 244 = N - 24](https://tex.z-dn.net/?f=2F%20-%20244%20%3D%20N%20-%2024)
![2F = N + 220](https://tex.z-dn.net/?f=2F%20%3D%20N%20%2B%20220)
Using the 'F' value from the first equation, we have:
![6N = N + 220](https://tex.z-dn.net/?f=6N%20%3D%20N%20%2B%20220)
![5N = 220](https://tex.z-dn.net/?f=5N%20%3D%20220)
![N = 44\ books](https://tex.z-dn.net/?f=N%20%3D%2044%5C%20books)
![F = 3N = 132\ books](https://tex.z-dn.net/?f=F%20%3D%203N%20%3D%20132%5C%20books)
The total number of books is:
![F + N = 132 + 44 = 176\ books](https://tex.z-dn.net/?f=F%20%2B%20N%20%3D%20132%20%2B%2044%20%3D%20176%5C%20books)
