percent ---------------- quantity
\n" ); document.write( "Alcohol I 25 ---------------- 6 ml
\n" ); document.write( "Alcohol II 5 ---------------- x ml
\n" ); document.write( "Mixture 13 ---------------- 6 + x ml
\n" ); document.write( "
\n" ); document.write( "25 *6+5x = 13 ( 6 + x )
\n" ); document.write( "150 + 5 x = 78 + 13 x
\n" ); document.write( "5 x + -13 x = 78 - -150
\n" ); document.write( "-8 x = -72
\n" ); document.write( "/ -8
\n" ); document.write( "x = 9
\n" ); document.write( " 9 ml of 5 % Alcohol II
