Answer:
19
Step-by-step explanation:
9 - (-10) = ?
To do this, we need to use the additive inverse and the method of K(eep)F(lip)C(hange)
So, the problem becomes: 9 + 10 = ?
Do the math, and you get your answer of 19.

Answer:
![\large \boxed{{y=18}}](https://tex.z-dn.net/?f=%5Clarge%20%5Cboxed%7B%7By%3D18%7D%7D)
Step-by-step explanation:
![1(y+3)=2(y+-4)+- 7](https://tex.z-dn.net/?f=1%28y%2B3%29%3D2%28y%2B-4%29%2B-%207)
Expand brackets.
![y+3=2y-8+- 7](https://tex.z-dn.net/?f=y%2B3%3D2y-8%2B-%207)
Simplify.
![y+3=2y-15](https://tex.z-dn.net/?f=y%2B3%3D2y-15)
Add -y and 15 on both sides.
![y+3-y+15=2y-15-y+15](https://tex.z-dn.net/?f=y%2B3-y%2B15%3D2y-15-y%2B15)
Simplify.
![3+15=2y-y](https://tex.z-dn.net/?f=3%2B15%3D2y-y)
![18=y](https://tex.z-dn.net/?f=18%3Dy)
No, because it has a constant rate of change
