3x/(x-2) = 6/(x-2)
\n" ); document.write( ".
\n" ); document.write( "at first glance,,,3x=6,,,or x=2
\n" ); document.write( ".
\n" ); document.write( "However, this results in 6/0=6/0,,,,or undefined
\n" ); document.write( ".
\n" ); document.write( "Starting over by cross multiplying,
\n" ); document.write( ".
\n" ); document.write( "3x(x-2) = 6(x-2)
\n" ); document.write( ".
\n" ); document.write( "3x^2 -6x = 6x -12
\n" ); document.write( ".
\n" ); document.write( "3x^2 =12
\n" ); document.write( ".
\n" ); document.write( "x^2 =4
\n" ); document.write( ".
\n" ); document.write( "x= +/- 2
\n" ); document.write( ".
\n" ); document.write( "checking x=2,,,,,3(2)/(2-2) = 6/(2-2),,,,or 6/0=6/0,,,undefined
\n" ); document.write( ".
\n" ); document.write( "checking x=-2,,,,,3(-2)/(-2-2) =6/(-2-2),,,or -6/-4=+6/-4,,,,not true
\n" ); document.write( ".
\n" ); document.write( "net result, x=2 results in undefined answer,,,while x=-2, is not true
