I have revently been trying to boost one of my other accounts so I can try and get something above bronze. I have been losing a lot kf games based upon fighting against 2 people (a tank like 
and a fighter/marksmen like 
). I just want to know how to play aginst these lanes, anyone know what to do? (Games where my jungler doesnt help and my other lanes dont do well enough to carry)
Farm as hard as you can don't engage them, don't get ganked by mid or whatever. Hold onto tower as long as possible. When it goes, leave top, forget it. Roam to try to take an objective, feed off an enemy, or get an ally fed. Fight the good fight. I give you my feels. Only saving grace is your xp and gold advantage over theirs due to how minions distribute their resources amongst number of champions present.
where are you experiencing this 1 v 2 lane? i didnt know anyone still did it personally, my go 2 top laner for bad situations is garen this guy can definitely hold his own against 2 top laners
Renekton and Heimerdinger can actually kill people in 1v2 lanes on level 6 due to the experience and gold lead you'll get. Just make sure you bring Teleport so you can actually buy items without instantly losing your tower.
Hug your tower and tell your jungler to farm enemy jungle and gank mid/bot nonstop and get early dragon. By midgame you** WILL** have a significant gold/xp advantage over them.
Take teleport.
Let them stupidly push minions into your tower. Average players will do this by default.
As long as you get exp and avoid feeding your team should win 4v3 and or help you soon.
Consider 
start or 
If it's versus intermediate bots they'll push if you don't show in lane right away. Players will probably do this too. You just want to be in exp range of creeps dying.
You can sort of practice being 1v2'd in an intermediate bot game if your team decides to use a jungler. I'm not saying it'll prepare you for LCS 1v2 lane swaps, just normal play
If you lose first tower it's not a big deal. Dying and losing exp is a bigger deal.
