\r\n" );
document.write( "Let A be Ana's age and J be the Jamie's age.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then from the condition, you have this system of equations\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    A - 5 = 2*(J-5)     (1)\r\n" );

document.write( "    A - 10 = J + 15.    (2)\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "To solve it,  express  A = 2J - 10 + 5 = 2J - 5  from the first equation and then substitute it into the second equation.\r\n" );
