logx + log2x = log50

Is this correct?

3x = 50

3/3 = 50/3

x = 16.67 (approx.)

It is difficult to read the post.
Do you mean $\log(x)+\log(2x)=\log(50)?$
If not, what?

That exactly the way the question reads logx + log2x = log50 there are no brackets solve for x.

Please take more care in the way you post mathematics.
You must grouping symbols. Logarithm is function and follows proper function notation.

Why not learn to post in symbols? You can use LaTeX tags.
[tex]\log(x)[/tex] gives $\log(x)$ .

Seriously this is the exact way it is asked :

Solve the following equation for x.

logx + log2x = log50

there are no brackets or bases or anything else this is the way it has been asked, i understand what you are saying it is a function and has rules etc. but this is the way it has been asked.
