You can put this solution on YOUR website!
Let x = time it will take them together to do the job.\r
\n" ); document.write( "\n" ); document.write( "1/8 = amount of the job the experienced accountant can do in 1 hour.
\n" ); document.write( "1/23 = amount of the job the novice can do in 1 hour.
\n" ); document.write( "1/x = amount of the job they can do together.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"1%2F8+%2B1%2F23=+1%2Fx\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Multiply both sides by the LCD which is \"23%2A8%2Ax\"\r
\n" ); document.write( "\n" ); document.write( "\"1%2F8+%2B1%2F23=+1%2Fx\"
\n" ); document.write( "\"23%2A8%2Ax+%2A%281%2F8%29+%2B+23%2A8%2Ax%2A%281%2F23%29+=+23%2A8%2Ax%2A%281%2Fx%29\"\r
\n" ); document.write( "\n" ); document.write( "\"23x+%2B+8x+=+23%2A8\"
\n" ); document.write( "\"31x+=+184\"
\n" ); document.write( "\"x+=+184%2F31=+5.935\" approximately!\r
