It does make sense.....

Split into two inequalities: $2x \ge 3x+6$ and $3x+6 \ge 6x-6$ and solve each one.

If $2x \ge 3x+6$, solving for x we get $x \le -6$.

For the second inequality, $3x+6 \ge 6x-6$, subtract 3x from both sides to get $6 \ge 3x-6$. Add 6 to both sides to get $12 \ge 3x \Rightarrow x \le 4$.

The solution set is the intersection of the sets defined by $x \le -6$ and $x \le 4$ (because x needs to satisfy both inequalities). This inequality follows the transitive property, so we do not need to worry about the inequality $2x \ge 6x-6$. The solution set is $x \le -6$.
