\r\n" );
document.write( "Let \"x\" be the amount (in kilograms) of Kenyan coffee to mix.\r\n" );
document.write( "\r\n" );
document.write( "Then the amount of the Venezuelan coffee is (192-x) kilograms.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The \"price\" equation is\r\n" );
document.write( "\r\n" );
document.write( " = 12.    (1)\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Why is it the \"price\" equation ?\r\n" );
document.write( "\r\n" );
document.write( "Because the numerator is the cost (in dollars) of combined 192 kilograms.\r\n" );
document.write( "Divided by 192, it is the price per kilogram.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It is your basic equation.  As soon as you got it, the setup is completed.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "To solve the equation (1), multiply both sides by 192. You will get\r\n" );
document.write( "\r\n" );
document.write( "10x + 13*192 - 13x = 12*192,\r\n" );
document.write( "\r\n" );
document.write( "-3x = 12*192 - 13*192 = -192  ====>  x =  = 64.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Answer.  64 kilograms of the Kenyan coffee must be mixed with 192-64 = 128 kilograms of the Venezuelan coffee.\r\n" );
