86. Decode the numerical riddle

$$
\overline{\text { SLOV, O }}+\overline{\text { SLOV, O }}=\overline{\text { PESNYA }}
$$

(Different letters correspond to different digits, and the same letters correspond to the same digits.)
86. Let's write the addition in a column

Since the result is a whole number, then $O=5$. The letter П can only represent the digit 1, then $\mathrm{H}=0$. Since $\mathrm{C}>5$, we find by trial that $C=9, Л=4$ and so on. We get $9453.5+9453.5=18907$.
