Question 511474
Numerator is 4 less than denominator
.
{{{ (x-4)/x }}}
.
{{{ (2(x-4))/(x-2) + (x-4)/x = 3}}}
.
{{{ ( 2(x-4)*x + (x-2)(x-4) ) /  ( (x-2)*x ) = 3}}}
.

{{{ ( 2(x-4)*x + (x-2)(x-4) ) = 3*(x-2)*x }}}
.
{{{ 2x^2 -8x + x^2 -6x + 8 = 3x^2 -6x}}}
,
{{{ 2x^2 -8x + x^2 -6x + 8 -3x^2 +6x = 0}}}
.
{{{ -8x +8 = 0}}}
.
{{{ -8x = -8}}}
.
{{{x = 1}}}
.
Done.
