Add their rates of painting
\n" ); document.write( "Tyrone's rate: ( 1 kitchen )/(7 hrs)
\n" ); document.write( "Shauna's rate: ( 1 kitchen )/(6 hrs)
\n" ); document.write( "Rare together: ( 1 kitchen )/(t hrs)
\n" ); document.write( " $\"+1%2F7+%2B+1%2F6+=+1%2Ft+\"$
\n" ); document.write( "Multiply both sides by $\"+42t+\"$
\n" ); document.write( " $\"+6t+%2B+7t+=+42+\"$
\n" ); document.write( " $\"+13t+=+42+\"$
\n" ); document.write( " $\"+t+=+42%2F13+\"$ hrs \n" ); document.write( "
