Follow these steps
a) lose the denominator by multiplying both sides by 'x'
b) Take everything on the right-hand side and subtract it from both sides
You will be left with a quadratic function of 'x' equal to 0
c) factorise that function of 'x' into the form (ax +- b)(cx +- d)
If two expressions multiplied together = zero, then one of them must be 0
so either (ax +- b) = 0
or (cx +- d) = 0
d) Solve each of those for the two possible answers.
If you cannot factorise the quadratic, then use the formula for solving quadratics:
x = (-b +- SQR(b^2 -4ac)) / 2a
(I hope I have remembered that correctly from over 40 years ago)
