Follow the acid.
\n" ); document.write( "Start with 20%x acid
\n" ); document.write( "Add 80%(200-x) acid
\n" ); document.write( "End up with 50%(200)acid
\n" ); document.write( "EQUATION:
\n" ); document.write( "20x +80(200-x) = 50(200)
\n" ); document.write( "20x +16000 - 80x = 10000
\n" ); document.write( " -60x = -6000
\n" ); document.write( "x = 100 liters of 20% solution
\n" ); document.write( "200-x= 100 liters of 80% solution\r
