\r\n" );
document.write( "Let x be the amount (the volume in milliliters) of the 5% solution to be mixed.\r\n" );
document.write( "\r\n" );
document.write( "Then the volume of the 1% solution is 100-x milliliters.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then your \"concentration\" equation is\r\n" );

document.write( "100-x + 5*x = 200,\r\n" );

document.write( "4x = 100  ---->  x =  = 25.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Answer.  25 milliliters of the 5% solution must be mised with 100-25 = 75 milliliters of the 1% solution.\r\n" );
