\n" ); document.write( "\n" ); document.write( "Princess Margaret hospital received a shipment of \"13\"​-milligram doses of a medicine. \r
\n" ); document.write( "\n" ); document.write( "Each \"13\"​-milligram package was repacked into two smaller doses of unequal size and labeled packet \"A\" and packet\"+B\". \r
\n" ); document.write( "\n" ); document.write( "\"A+%2BB=13\"
\n" ); document.write( "\"A+=13-B\"............eq.1\r
\n" ); document.write( "\n" ); document.write( "The hospital then used \"19\" doses of packet \"A\" and \"17\" doses of packet \"B\" in one week. The hospital used a total of \"243\" milligrams of the medicine during that week.\r
\n" ); document.write( "\n" ); document.write( "\"19A+%2B17B=243\".............eq.2,..substitute \"A\" from eq.1
\n" ); document.write( "\"19%2813-B%29+%2B17B=243\"
