Spremenljivka x ne more biti enaka nobeni od vrednosti \frac{1}{2},1, ker deljenje z vrednostjo nič ni določeno. Pomnožite obe strani enačbe s/z \left(x-1\right)\left(2x-1\right).

$$0=0$$

To je za vsak x »true«.

$$x\in \mathrm{R}$$

Spremenljivka x ne more biti enaka nobeni od vrednosti \frac{1}{2},1,-4,4.
