You can put this solution on YOUR website!
Aaron's rate + Karen's rate = combined rate
\n" ); document.write( "(1 house / 12 hrs) + (1 house / 6 hrs) = 1 house / x hours
\n" ); document.write( "\"1%2F12+%2B+1%2F6+=+1%2Fx\"
\n" ); document.write( "multiply both sides of the equation bt 12
\n" ); document.write( "\"1+%2B+2+=+12%2Fx\"
\n" ); document.write( "\"x+=+12%2F3\"
\n" ); document.write( "\"x+=+4\"hrs answer
