You can put this solution on YOUR website!
1/x+1/y=3
\n" ); document.write( "1/x-1/y=3
\n" ); document.write( "--------
\n" ); document.write( "Sub r for 1/x, s for 1/y
\n" ); document.write( "r + s = 3
\n" ); document.write( "r - s = 3
\n" ); document.write( "---------- Add
\n" ); document.write( "2r = 6
\n" ); document.write( "r = 3 --> x = 1/3
\n" ); document.write( "-----------
\n" ); document.write( "s = 0 --> y = 1/0
\n" ); document.write( "y is undefined --> no solution. \n" ); document.write( "
