Hi there,
\n" ); document.write( "Two numbers p and q have a sum of 27
\n" ); document.write( "p + q = 27......(1)
\n" ); document.write( "and a difference of 9.
\n" ); document.write( "p - q = 9.......(2)
\n" ); document.write( "...........
\n" ); document.write( "p + q = 27......(1)
\n" ); document.write( "p - q = 9.......(2)
\n" ); document.write( "Add Eqs(1) + (2)
\n" ); document.write( "2p = 36
\n" ); document.write( "p = 18.
\n" ); document.write( "Substitute p = 18 into
\n" ); document.write( "Eq (1)
\n" ); document.write( "p + q = 27......(1)
\n" ); document.write( "18 + q = 27
\n" ); document.write( "q = 27 - 18
\n" ); document.write( "q = 9.
\n" ); document.write( ".......
\n" ); document.write( "p = 18
\n" ); document.write( "q = 9
\n" ); document.write( "Hope this helps :-) \n" ); document.write( "
