The answer is obvious just by inspection. 3+2=5 and 4+2=6.


\n" ); document.write( "By algebra.


\n" ); document.write( "\"%283%2Bn%29%2F%284%2Bn%29=5%2F6\"


\n" ); document.write( "Cross multiply


\n" ); document.write( "\"6%283%2Bn%29+=+5%284%2Bn%29\"


\n" ); document.write( "Multiply each number by what's inside the ()


\n" ); document.write( "\"18+%2B+6n+=+20+%2B+5n\"


\n" ); document.write( "Subtract 5n from both sides, subtract 18 from both sides.


\n" ); document.write( "n = 2\r
\n" ); document.write( "\n" ); document.write( "
