There are 10 questions in the attached image. I cannot solve 10 questions for you in one. I suggest that you submit the questions one by one if you really need each one solved.
Here I solve in detail two of the questions and explain the solution. With this explanation you should be able to understatnd how to answer all the questions.
13) a - 6 ≤ 15 + 8a
=> a - a - 6 - 15 ≤ 15 - 15 + 8a - a
-21 ≤ 7a
7a ≥ - 21
a ≥ - 21/7
a ≥ - 3
So, the solutions are all the number on the real line equal or greater than - 3.
14) 13 + 2v - 8 + 6 > - 7 - v
=> 13 - 13 + 2v + v - 8 + 8 + 6 - 6 > - 7 - 13 + 8 - 6 - v + v
=> 3v > - 18
=> 3v > -18 / 3
=> v > - 6
Therefore, the solutions on the real line are all the real numbers greater than - 6.
