It seems you have uploaded a photo of a mathematical problem in Russian. It includes some equations, which seem to be tasks related to algebra or rational functions. Here's a translation of the problems to help you better understand them:

1. Variant 1
   • a) $\frac{3x^2 - 5x - 2}{2 - x} = 0$
   • b) $\frac{3x - 2}{x - 1} + \frac{x - 4}{x + 3} = \frac{3x^2 + 1}{(x - 1)(x + 3)}$
   • c) $\frac{2}{x - 5} - \frac{4}{x + 5} = \frac{3}{x^2 - 25}$

Do you need help solving any of these problems or understanding the steps involved?

Let me know if you'd like detailed solutions or have any specific questions about these equations.
