#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!
