2=6x/(6+x) now cross multiply
\n" ); document.write( "2(6+x)=6x
\n" ); document.write( "12+2x=6x
\n" ); document.write( "6x-2x=12
\n" ); document.write( "4x=12
\n" ); document.write( "x=12/4
\n" ); document.write( "x=3 hours for the other machine working alone.
\n" ); document.write( "proof
\n" ); document.write( "6*3/(6+3)=2
\n" ); document.write( "18/9=2
