\n" ); document.write( "more than the second. Find the numbers.
\n" ); document.write( "----------
\n" ); document.write( "Call them x, y & z
\n" ); document.write( "x + y + z = 8
\n" ); document.write( "x - y + z = 4
\n" ); document.write( "x - z = y + 2 --> x - y - z = 2
\n" ); document.write( "--------
\n" ); document.write( "x + y + z = 8
\n" ); document.write( "x - y + z = 4
\n" ); document.write( "x - y - z = 2
\n" ); document.write( "-----------
\n" ); document.write( "Add eqns 1 & 3
\n" ); document.write( "x + y + z = 8
\n" ); document.write( "x - y - z = 2
\n" ); document.write( "-------------
\n" ); document.write( "2x = 10
\n" ); document.write( "x = 5
\n" ); document.write( "=====================
\n" ); document.write( "Add eqns 1 & 2
