\n" ); document.write( ".
\n" ); document.write( "Let x = the number
\n" ); document.write( "then
\n" ); document.write( "1/x = the reciprocal (because x * 1/x = 1)
\n" ); document.write( ".
\n" ); document.write( "7(1/x) + 5(1/x) = 4
\n" ); document.write( "7/x + 5/x = 4
\n" ); document.write( "multiplying both sides by x:
\n" ); document.write( "7 + 5 = 4x
\n" ); document.write( "12 = 4x
\n" ); document.write( "3 = x
\n" ); document.write( ".
\n" ); document.write( "The number is 3 \n" ); document.write( "
\n" );
