Answer 13

There is one small mistake, after dividing by 2 you'd get
\[-x\le -6\]
Now you multiply both sides by -1, this will change the inequality sign
\[x\ge 6\]

Answer 14

\[-2> -3\]
multiply both sides by -1
\[2<3\]

Answer 15

I did get -6, it just didnt show up too well, haha

Answer 16

did you understand the last step ? @unheard

Answer 17

No, I did not understand the very last step

Answer 18

-2x + 1 <= - 11
-2x <= - 11 - 1
-2x <= -12
x >= 6

Answer 19

You had
\[-x\le -6\]
Now you multiply both sides by -1, which inverts the sign
\[x\ge 6\]
See my post above about -2>-3
Do you agree with that?

Answer 20

Ohh, Okay. I understand now. Thank you.

Answer 21
