document.write( "the system of linear equations representing the problem...
\n" );
document.write( " x + y = 20
\n" );
document.write( " x - y = 16
\n" );
document.write( "Solving by elimination method:
\n" );
document.write( " 2x = 36
\n" );
document.write( "  x = 18  and y = 2 (substituting x into the 1st Eq) \n" );
