You can put this solution on YOUR website!
Hint: Add the two equations to get\r

\r\n" );
document.write( "\r\n" );
document.write( "    x + y = 12\r\n" );
document.write( "+   x - y = 4\r\n" );
document.write( "---------------\r\n" );
document.write( "   2x + 0y = 16\r\n" );
document.write( "\r\n" );
document.write( "

\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So we now have the equation 2x = 16. Solve this for x. Once you have the solution for x, use it to find y. \n" ); document.write( "
