Let X be the liters of 10% solution.
\n" ); document.write( " $\"4%287%29%2B10%28X%29=6%287%2BX%29\"$
\n" ); document.write( " $\"28%2B10X=42%2B6X\"$
\n" ); document.write( " $\"4X=14\"$
\n" ); document.write( " $\"X=7%2F2=3.5\"$
\n" ); document.write( "3.5 liters of 10% solution will mix to give a 6% solution.
\n" ); document.write( " \n" ); document.write( "
