independence of valuations

Let $|\cdot|_{1}$ , …, $|\cdot|_{n}$ be non-trivial (i.e., they all have also other values than 0 and 1) and pairwise non-equivalent valuations of a field $K$ , all with values real numbers. If $a_{1}$ , …, $a_{n}$ are some elements of this field and $\varepsilon$ is an arbitrary positive number, then there exists in $K$ an element $y$ which satisfies the conditions

$\displaystyle\begin{cases}|y-a_{1}|_{1}<\varepsilon,\\ \qquad\vdots\\ |y-a_{n}|_{n}<\varepsilon.\\ \end{cases}$
