Question

Can ya'll please check this for me ?!?!?! I will have to post the equation (s) below

Answer 1

\[\left| 3-9x \right| \le 39\]

I got\[x \le -4 ~~or ~~x \ge -4 2/3\]

Answer 2

that is supposed to be -4 and 2/3

Answer 3

|3-9x|<=39 this implies -39<=3-9x<=39 divide by 3 then we have -13<=1-3x<=13
This implies -14<=-3x<=12
Divie by -3 and the inequality changes direction
this implies 14/3>=x>=-4.@Bookworm14
