A first number [x] plus [+] twice a second number [2y] is [=] 11.
\n" ); document.write( "

\r\n" );
document.write( "x + 2y = 11\r\n" );
document.write( "

\n" ); document.write( "Twice the first number [2x] plus [+] the second [y] totals [=] 31.
\n" ); document.write( "

\r\n" );
document.write( "2x + y = 31\r\n" );
document.write( "\r\n" );
document.write( "So the system of two equations with 2 unknowns is\r\n" );
