$begingroup$
I have such inequality:
$$-0.1b le frac{y}{x} le 0.1b$$
How to solve it in terms of x to have something like this:
$$ ? le x le ? $$
Thanks for any help.

You'd take the reciprocal of each term in the inequality, then multiply each term by $y$.
Note, however, taking the reciprocal reverses the order of the inequality symbols. For example, notice:
$$1 < 2 < 3 ;;; Leftrightarrow ;;; 1 > frac{1}{2} > frac{1}{3}$$

I honestly wouldn't know myself; this is a fairly basic technique taught in your typical algebra class in elementary or middle school. So I guess some textbook of the sort, or perhaps some videos on Khan Academy might help? (Not sure if Khan Academy covers this particular topic but I'm pretty sure they have pretty much everything from the standard K-12 math curriculum on their site.)
