\r\n" );
document.write( "Let x be that amount under the question, in cubic centimeters.\r\n" );
document.write( "\r\n" );
document.write( "Then you have this equation\r\n" );
document.write( "\r\n" );
document.write( "0.12x + 0.22*80 = 0.16*(80+x),\r\n" );
document.write( "\r\n" );
document.write( "which represents the salt mass balasnce.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "To solve the equation, multiply its both sides by 100, to get it easier. You will get\r\n" );
document.write( "\r\n" );
document.write( "12x + 22*80 = 16*80 + 16x,\r\n" );
document.write( "\r\n" );
document.write( "22*80 - 16*80 = 16x - 12x,\r\n" );
document.write( "\r\n" );
document.write( "4x = 6*80  ====>  x =  = 6*20 = 120.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Answer.  120 cc of the 12% saline solution must be added.\r\n" );
