How can I improve my gameplay to carry myself out of Bronze League? [closed]

I've been playing League for years, since season 1. I'm not an amazing player, but I'm not terrible either. I'm attempting to get out of Bronze League in ranked play, but I'm having a very difficult time doing so. I'm very consistent in my games, particuarly when I ADC as Ezreal. My stats for him over 41 ranked games are K6.7\D3.4\A9.0 with a CS of 153.3. Again, while not spectacular I'm not bad at all either.

My issue is the rest of my team, and how I can interact with them or improve my gameplay enough to carry them entirely. I often have players that die upwards to 10 times, often not killing more than 3 players in the game. Now I know kills don't win games, objectives do, and I frequently communicate, attemping to focus our efforts on said objectives. When people feed like this however, generally opposing players have grown so strong that it becomes extremely difficult to retain map and objective control.

How can I rally my team to play better, and\or improve my gameplay in such a way that it will enable me to carry them entirely if need be?

Generic answers such as 'be more aware', or 'farm better', are useless as these are skills that can always obviously be improved. I'm looking for more of a social idea or some particular set of skills not previously mentioned that will allow me to rise above the curve.
