\n" );
document.write( "Hi
\n" );
document.write( "y = 2x+1  
\n" );
document.write( "x+y = 3y-20   |good work!
\n" );
document.write( "x  + (2x+1) = 3(2x+1) - 20   |substituting for y
\n" );
document.write( "solving for x
\n" );
document.write( " 3x + 1 = 6x + 3 - 20
\n" );
document.write( "      18 = 3x
\n" );
document.write( "       x = 6  and y = 13  (2x+1)\r
