\n" ); document.write( "Let x = pints of 10% solution added
\n" ); document.write( "then\r
\n" ); document.write( "\n" ); document.write( ".10x + .08(6) = .09(6 + x)\r
\n" ); document.write( "\n" ); document.write( ".10x + .48 = .54 + .09x
\n" ); document.write( ".01x + .48 = .54
\n" ); document.write( ".01x = .06
\n" ); document.write( "x = .06/.01
\n" ); document.write( "x = 6 pints
