How to win 12 games in a row?

title ^^ ^^^^ i just deranked to silver 2 yay great game i was silver 1 yesterday with 99 lp but riot decided to punish me so i lost a couple of games and now im back at silver 2 at 75 lp meaning that i have to win 12 games in a row in order to get gold which i was 1 lp from getting into promotion to. honestly it can't be that hard seeing as i demoted from silver 1 99 lp to here in 1-2 days so i just have to get fast back up again so i need some tips or strategies to do so? it is a bit hard but im sure its possible otherwise riot wouldn't have made their ranked system like this
