I’m struggling with the Algebra section on page 67 version 2 of the OG Quant practice book. Is this normal?

I’m on week 6 of the two month plan and a lot of these problems seem tough to me. Just need some words of encouragement if possible

Can you post the question?

It’s difficult to post but I’m having trouble with question numbers 13,14,15, and 16.
