How to climb iron

Posted this on main league figure I would here too

Hi guys, I am a jungle main, mostly viego and wukong and idk why but my game started me in Iron a while back and I literally for the life of my can't get a single win. Not to sound high and mighty be it is straight up not me I have games where I drop 20 as viego with barely any deaths but it's a loss. The past 3 games tonight I had a yuumi top lane, and two games of feeding midlaners that made the game completely unplayable. I understand the game and how to go about obj and when to back off and farm, I'm not quite sure what can be done to climb. Any advice?
