+118723 i cannot answer your question - the forum code will not allow it.
I think it is because you have put in a title that is not in ordinary print. Sometimes this happens.
Your question is
$$\frac{x}{2z}-2b=0$$
Lösungsmenge $$\left\{\dfrac{0,3}{b}\right\}$$
-------------------------------------
I do not understand what you mean by
Solution set $$\left\{\dfrac{0,3}{b}\right\}$$ ???
-----------------------------
Lösungsmenge $$\left\{\dfrac{0,3}{b}\right\}$$ ???
+118723 Maybe a person who speaks French or German might be able to help with the translation ?
Can anyone help, it is not making sense to me. 
Quelqu'un peut aider, il ne fait pas sens pour moi.

I am getting criptic private messages here. Mmm
Servus,
3
fraction bar -2b= 0
5*z
z=???
$$\frac{x}{2z}-2b=0$$
$$\\\frac{3}{-2b}=0\\$$ This is impossible - you cannot divide 3 by ANYTHING and get 0!
