The second volume of the second day of junior high school mathematics gold medal example
If the bronze medal "X" is set, the gold medal is 2X+3. If the equation holds, it is X+ 199+2X+3 = 4 16.
If you don't use the equation, divide 416-19 = 297 by 297-3=294 to get 98 98, which is the number of bronze medals, and 98*2+3 is the number of gold medals.
