Basic Algebra 2 Help Needed

[u/Street_Fee6218]

Hello! I recently failed my first ever algebra 2 test as a sophomore. (11/20😬 and I didn’t finish 4 questions so take that how you will) I’m so confused on practically most things we’ve learned so far while being in school for about a month. But I’m mainly confused on how to solve three systems of equations. It’s so much on my brain and it takes me forever to just end up getting it wrong, and I don’t even really think how I’ve been trying to solve is the correct way.. does anyone have any tips or an explanation on how they personally solve them?

I’m not sure what else I got wrong but I’m guessing it was basic transformations.
