if you like you can start by flipping both sides and solve \[\frac{x+2}{4}=\frac{x}{2}\]

or just go right to \[4x=2(x+2)\]

\[\frac{a}{b}=\frac{c}{d}\iff ad=bc\] is always true yes you are solving for \(x\) there is not other variable there

x=2

yes that is correct if \(x=2\) then both sides of the equal sign are \(1\)

Is it extraneous? lets plug it in. \[\frac{4}{\color{red} {2}+2}=\frac{2}{\color{red} {2}}\]\[\frac{4}{4}=\frac{2}{2}\]So, yes, it is extraneous.
