Answer 5

I got:
\[\left\{ x \in \mathbb{R} | x \le \frac{76}{7} \right\} \]

Answer 6

You just solve for x.
Distribute:\[-8-33x-77 \le -40x-9\]
\[-33x-85 \le -40x-9\]
\[7x \le 76\]
\[x \le \frac{76}{7}\]
The beginning of the set just tells you that its any real number (which it is)

Answer 7

Alternative form : \[\left \{ x \in \mathbb{R} | x \in ]- \infty ; 76/7 ] \right\}\]
