In the Olympic Games, one country has won twice as many silver medals as bronze medals. Archie found that if the country gets 1 more gold medal, then the number of gold medals is the sum of the number of silver medals and the number of bronze medals; May I ask: How many gold medals has this country won in total?
在奥运会上有一个国家得的银牌数是铜牌数的2倍．阿奇发现如果这个国家再得到1块金牌，那么金牌数就是银牌数和铜牌数的和；如果有1块金牌变成银牌，那么金牌数和银牌数将一样多．请问：这个国家一共得到多少块金牌？
