Okay, here we have this:

Considering the provided information, we are going to identify wich equation applies, so we obtain the following:

x+19=2x

Where x represents the uknown number. Then finally we obtain that the correct equation is the third one.

Now, let's find the missing number solving the equation:

\begin{gathered} x+19=2x \\ 19=2x-x \\ 19=x \end{gathered}

Finally we obtain that the number is equal to 19.
