Setup and solve the absolute​ value​ equation.​​ Don't forget to check​ for​ extraneous​​ solutions!

The absolute​ value​ of​​ (three x​​ plus​ five) equals twelve x plus 8.

|3x + 5| = 12x + 8
3x + 5 = 12x + 8
3x - 12x = 8 - 5
-9x = 3
x = -3

Checking for extraneous solutions:

|3(-3) + 5| = 12(-3) + 8
|-9 + 5| = -36 + 8
|-4| = -28
4 = 28

This is not true, so the solution is x = -3.
AAAaannndd the bot gets it wrong yet again!
even fails its own arithmetic and logic!

|3x + 5| = 12x + 8

either x > -5/3
3x+5 = 12x+8
9x = -3
x = -1/3

OR x x < -5/3
-(3x+5) = 12x+8
15x = -13
x = -13/15
This solution is extraneous
The odd thing is that this same question was posted a while back and I corrected it (the same as your answer),
and now the bot is doing it in exactly the same incorrect way,

with the bot's solution even containing this morsel:
...
-9x = 3
x = -3

Who generates these questions which always have the same "poster" as the source and are of the same type ? Is this part of the NEW Jishka ? (LLC)
I am getting very tired of continually having to correct the answers given
by the robot.
