Add their rates of working to get their rate
\n" ); document.write( "working together.
\n" ); document.write( "Let $\"t\"$ = time it takes the other printer
\n" ); document.write( "to do a job
\n" ); document.write( " $\"+1%2F9+%2B+1%2Ft+=+1%2F6+\"$
\n" ); document.write( "Multiply both sides by $\"18t\"$
\n" ); document.write( " $\"+2t+%2B+18+=+3t+\"$
\n" ); document.write( " $\"+t+=+18+\"$
\n" ); document.write( "It takes the other printer 18 days
\n" ); document.write( " to do the work by himself \n" ); document.write( "
