x-7/x
\n" ); document.write( "(x-7+3)/(x-9)=3/2
\n" ); document.write( "(x-4)/(x-9)=3/2
\n" ); document.write( "2*(x-4)=3*(x-9)
\n" ); document.write( "2x-8=3x-27
\n" ); document.write( "x=19
\n" ); document.write( "12/19 original fraction
\n" ); document.write( "check
\n" ); document.write( "12/19
\n" ); document.write( "15/10=3/2
\n" ); document.write( "ok
