6x/(6+x)=4 cross multiply
\n" ); document.write( "6x=4(6+x)
\n" ); document.write( "6x=24+4x
\n" ); document.write( "6x-4x=24
\n" ); document.write( "2x=24
\n" ); document.write( "x=24/2
\n" ); document.write( "x=12 hours for Steve to process the paper alone.
\n" ); document.write( "proof
\n" ); document.write( "6*12/(6+12)=4
\n" ); document.write( "72/18=4
\n" ); document.write( "4=4
