for example I have the equation $2y=4x$ and I want to solve it for $x$, (sure, $x = \frac{1}{2} y$, but how can I just write, that I want to solve it for $x$?

You can always use as many words as you like when writing mathematics. It just makes things cumbersome if you use words instead of symbols when dealing with complicated problems, but that doesn't change the content of what you're writing. So, here you can write "I want to solve two times y equals four times x for x." Or you could write "I want to solve 2y=4x for x."
