Using multiple lines, e.g. pasting from clipboard?

Can one use multiple lines, e.g. pasting the clipboard into Wolfram|Alpha and solve it?
(For example function calculations for a given value)

I have much more elaborate applications but to demo a simple example would be:

Value=2

Answer=3*Value

A demo of how I do it now is:
Evaluate_Calculator

How could one do that in WolframAlpha and does one use line breaks such as , or ; ?

I spent tried several hours before asking here.

Thanks.
