how to win games ( serious )

First of all, if you wanna look at my games, here are my Main & smurf OpGG. I usually don’t like to smurf, but i was so frustrated that i create one and still got hard inted:

Main ( EUW ) : Neicogotbanned#WTF Smurf ( EUW ) : Irelia#EGO

I mainly played Irelia on my smurf account, so i will summarize my problem for this account:

I always ( like 90% of the games ) win my lane relatively hard but i can’t carry games because my mates int super hard. If you take the last two ranked games for example, in the first game , i hard stomp my lane, have a major CS and kill lead , but my jngl goes 1/11, my top goes 3/14 and my bot is even. In the second game, i , again, hard stomp my lane against malzahar and again,

my team goes 5/10 5/10 2/9 etc.

I’m not saying i’m the god of Irelia and deserve to be challenger, but i dont understand how i am supposed to carry in fucking IRON gold and silver if at all times, my team runs it down more than the enemy.

You can start with the typical assumption „you just deserve that rank, you’re probably not good enough mechanically, your macro is probably shit so you give up important objectives or make your team lose“ and sometimes i, of course, make mistakes since im not higher than plat but i just dont know what to do if my team plays bad.

I would really appreciate advice on how to win these games or get better mates, i may even get some coaching to see my VODS so if you have a good source for that i’d appreciate that aswell.
