Solve the inequality to give you a simple expression for x. The just write {x | 'expression' }
$\displaystyle x \ge 6$ A little algebra will get you to this.
I need help please using set builder notation to describe a complete solution for this: 47-(2x+5) less than or equal to 3(x+2) +x I would say, $\displaystyle \{x\in\mathbb{R}\mid 47-(2x+5) \le 3(x+2) +x\}$
