5x-4 = $$J(x-1) = x^2/x (b :rn8toJ эпппкпишв) .+ 3. CORDSLIP DOOP:

The provided image contains mathematical expressions and some text in Russian. Due to the low quality and blurry nature of the image, it's challenging to accurately interpret all characters and symbols. However, I can decipher some parts: 1. A mathematical equation appears to be: `5x - 4 = f(x-1)` where 'f' might represent a function. However, the `$$` symbol before `J` and the `J` itself are unclear. The `f` could also be a poorly written '4'. 2. Another expression is `= x^2 / x`, which simplifies to `x` for `x != 0`. 3. There is a line that reads `:rn8toJ эпппкпишв) .+ 3. CORDSLIP DOOP:`. This appears to be Russian text written in reverse, and some characters are illegible. If reversed, it might read something like `3. POOD_PILLSCORN :` followed by other unclear text. The specific meaning is lost due to the image quality. Due to the illegibility of the text and symbols, a precise mathematical solution or a complete translation of the Russian text cannot be provided.
