Question 947904
{{{ a/(x-1) - 2/(x+1) = 4/(x-1)(x+1) }}}
{{{ (a(x+1))/((x-1)(x+1)) - (2(x-1))/((x+1)(x-1)) = 4/(x-1)(x+1) }}}
{{{ (a(x+1) - 2(x-1))/((x+1)(x-1)) = 4/(x-1)(x+1) }}}
So then,
{{{a(x+1)-2(x-1)=4}}}
{{{ax+a-2x+2=4}}}
{{{(a-2)x=4-2-a}}}
{{{(a-2)x=2-a}}}
{{{x=(2-a)/(a-2)}}}
{{{x=-1}}}
However, {{{x=-1}}} and {{{x=1}}} are not allowed solutions because of division by zero in the original equation.
So there is no solution.
