Question 365106
{{{x/(x+3) + 1/(x-3) = 1}}}
Use the common denominator, {{{(x-3)(x+3)}}}
.
.
{{{(x(x-3))/((x+3)(x-3)) + (x+3)/((x+3)(x-3)) = ((x+3)(x-3))/((x+3)(x-3))}}}
.
.
{{{(x(x-3)+ (x+3)- (x+3)(x-3))/((x+3)(x-3))=0}}}
.
.
{{{(x^2-3x+x+3-x^2+9)/((x+3)(x-3))=0}}}
.
.
{{{(-2x+12)/((x+3)(x-3))=0}}}
.
.
{{{(-2(x-6))/((x+3)(x-3))=0}}}
.
.
{{{x-6=0}}}
.
.
{{{highlight(x=6)}}}
