You can put this solution on YOUR website!
u = ounces of 15% acid
\n" ); document.write( "v = ounces of 25% acid\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%2815u%2B25v%29%2F20=21\" and \"u%2Bv=20\"
\n" ); document.write( "Solve these two simultaneous equations for u and v.\r
\n" ); document.write( "
