$x = 3/10$

$1/x + 2/x = 10$

First, let's get rid of the fractions by multiplying everything by $color(blue)x$ :
$x(1/x + 2/x = 10)$

$1 + 2 = 10x$

Simplify the left hand side:
$3 = 10x$

Now to solve for $x$ , divide both sides by $color(blue)10$ :
$3/color(blue)10 = (10x)/color(blue)10$

Therefore,
$3/10 = x$

$x = 3/10$

Hope this helps!
