$\"2%2F4%2B2%2Fx=1\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"2x%2F4x%2B8%2F4x=1\"$
\n" ); document.write( " $\"%282x%2B8%29%2F4x=1\"$ cross multiply
\n" ); document.write( " $\"2x%2B8=4x\"$
\n" ); document.write( " $\"8=2x\"$ divide each side by 2
\n" ); document.write( " $\"4=x\"$ so if we do it alone we can both get it done in 4 hours each, but if we do it together we get it done in 2 hours. So you can do it alone in 4. \n" ); document.write( "
