To solve these problems, we need to evaluate each algebraic expression by substituting the value of $x$.
Given:
$x = 10$
We will replace every "$x$" in the expressions with the number $10$ and then calculate the result.
Step-by-step Calculations:
1. $x - 2 \rightarrow 10 - 2 = 8$
2. $x + 9 \rightarrow 10 + 9 = 19$
3. $x - 9 \rightarrow 10 - 9 = 1$
4. $12 + x \rightarrow 12 + 10 = 22$
5. $x - 6 \rightarrow 10 - 6 = 4$
6. $6 + x \rightarrow 6 + 10 = 16$
7. $5 + x \rightarrow 5 + 10 = 15$
8. $x - 14 \rightarrow 10 - 14 = -4$
9. $1 - x \rightarrow 1 - 10 = -9$
10. $14 - x \rightarrow 14 - 10 = 4$
11. $13 + x \rightarrow 13 + 10 = 23$
12. $x - 12 \rightarrow 10 - 12 = -2$
13. $10 - x \rightarrow 10 - 10 = 0$
14. $4 + x \rightarrow 4 + 10 = 14$
15. $11 + x \rightarrow 11 + 10 = 21$
16. $x + 1 \rightarrow 10 + 1 = 11$
17. $x - 16 \rightarrow 10 - 16 = -6$
18. $x - 5 \rightarrow 10 - 5 = 5$
19. $14 + x \rightarrow 14 + 10 = 24$
20. $15 - x \rightarrow 15 - 10 = 5$
21. $x + 12 \rightarrow 10 + 12 = 22$
22. $16 - x \rightarrow 16 - 10 = 6$
23. $8 + x \rightarrow 8 + 10 = 18$
24. $8 - x \rightarrow 8 - 10 = -2$
25. $16 + x \rightarrow 16 + 10 = 26$
26. $x - 15 \rightarrow 10 - 15 = -5$
27. $x + 8 \rightarrow 10 + 8 = 18$
28. $13 - x \rightarrow 13 - 10 = 3$
