Thank you, Michelle

In his post, @consc198 solves inequality 7-3x < 31.
He did it FUNDAMENTALLY WRONG.
For correct solution to this inequality see what follows.
7 - 3x < 31.
Move 3x to the right side, changing the sign.
Move 31 to the left side, changing the sign.
You will get an equivalent inequality
7 - 31 < 3x,
-24 < 3x.
Divide both sides by 3
-8 < x.
ANSWER. The solution to inequality 7-3x < 31 is the set of real numbers x > -8.
Solved correctly.
As this person, @consc198, solves simple standard Math problems, he deserves to be excluded
from everywhere of an educational community, since he is not able to teach in a right way.
