You can put this solution on YOUR website!
Solve for X
\n" ); document.write( "1.
\n" ); document.write( " $\"x%2F3\"$ - 2 = 1
\n" ); document.write( "Add 2 to both sides:
\n" ); document.write( " $\"x%2F3\"$ = 1 + 2
\n" ); document.write( " $\"x%2F3\"$ = 3
\n" ); document.write( "Multiply both sides by 3
\n" ); document.write( "x = 3(3)
\n" ); document.write( "x = 9
\n" ); document.write( "Check solution in original equation

\n" ); document.write( "Factor the 3rd denominator
\n" ); document.write( " $\"x%2F%28%28x-2%29%29\"$ - $\"%28%28x%2B1%29%29%2Fx\"$ = $\"8%2F%28x%28x-2%29%29\"$
\n" ); document.write( "Multiply by the common denominator, namely x(x-2)
