I just played my first ranked game and both bot and top fed and i was about 6/2 at one point but I couldn't win vs. 4 other fed champs so my question is:
Will most games be like this until i get to like ~1300 elo?
If so how can i prepare? (like how many of each champ should i have and rune pages etc.)

It will be like this and worse.

Oh the fun....

Every game will be like this for either team until you learn how to either carry or feed consistently

ok i did great on my first and second time playing ranks. ill stop now before it gets worse. ty

I suggest playing alot since its close to the reset u can get as much ranked practice as u can and not worry so much about elo

Just play as much as possible before the reset so you can learn.

I'm avoiding ranked until the reset. I don't really like dealing with people who rage because they think they should be X elo but aren't because noobs and trolls are constantly sabatoging them.

May as well use the time to learn a few new champions and strategies before jumping back in after the season ends.

Find someone to duo Q with, at least then you can have some success
