Hello! Okay, so first things first, for these types of problems, you have to either divide if it's a whole number or multiply by the reciprocal (flipped over) if it's a fraction. Things you need to do is subtract the numbers with variables from the right side on both sides, then, subtract the whole number on the left to both sides, and then divide to get the answer. With that being said, here are the answers if you do them right.
1. -6 2/3
2. 0.8
3. -24
4. 11 2/5
5. -25
6. -2
7. 27
8. -21
9. 2
10. -10
11. 5
Note: I would've been able to explain to you better how you get these answers had there not been so many questions in one, but I tried my best.
