In words:
\n" ); document.write( "Let \"x\"= number of hours for Jim, Sue, and Tony to
\n" ); document.write( "fill pool working together
\n" ); document.write( "Jim's rate of filling + Sues rate of filling + Tony's rate of filling =
\n" ); document.write( "rate of all 3 filling pool together
\n" ); document.write( "\"1%2F.5+%2B+1%2F.75+%2B+1%2F1.5+=+1%2Fx\"
\n" ); document.write( "Multiply both sides by \"1.5x\"
\n" ); document.write( "\"3x+%2B+2x+%2B+x+=+1.5\"
\n" ); document.write( "\"6x+=+1.5\"
\n" ); document.write( "\"x+=+.25\" hr
\n" ); document.write( "All 3 filling pool together can do the job in 15 min
\n" ); document.write( "
\n" );
