document.write( "\r\n" );
document.write( "Let x be the Nica's age.\r\n" );
document.write( "\r\n" );
document.write( "Then the brother's age is 3x years.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "In 5 years, the brother's age will be (3x+5) years,\r\n" );
document.write( "\r\n" );
document.write( "while the Nica's age will be  x+5 years.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Therefore, the equation is\r\n" );
document.write( "\r\n" );
document.write( "    3x + 5 = 2*(x+5).\r\n" );
document.write( "\r\n" );
