It Will Give Only One Single Value As It Is A Linear Equation .
It Makes The Linear Equation $3 - 2x = 0$ . Where $x$ Has The Value $3/2$ .

yes....but there is no option of (3/2)

The problem asked to find the number of solution not the value of $x$ .

I would've gotten it wrong if it did have that answer choice.

is it possible to get the actual process you used to convert this into a linear equation?

$1=\frac { 1 }{ x } +\frac { 1 }{ 2x }$
$2x=1+2$
$x=\frac { 3 }{ 2 }$
