\fontsize{18}{10}{\textup{\textbf{The value of x is 5.}}}

Step-by-step explanation:

We know that

\log_ba=c~~~\Rightarrow a=b^c.

According to the given information, we have

\log_{10}2x=1.

Therefore, we get

2x=10^1\\\\\Rightarrow 2x=10\\\\\Rightarrow x=\dfrac{10}{2}\\\\\Rightarrow x=5.

Thus, the required value of x is 5.
