A student solved the following equation using the following steps:
4(2 - 3x) = x - 2(2x + 1)
8 - 3x = x - 4x - 2
8 - 3x = -3x - 2
x = 0

You didn't really expect the bot to be able to solve a grade 8
equation, did you ????
4(2 - 3x) = x - 2(2x + 1)
8 - 12x = x - 4x - 2
-9x = -10
x = 10/9
As you can see, the bot is wrong and could not detect the student's error.
