Which gets approved first, I-130 or I-485?

Hello there, I have a question about the immigration process and I'm a bit confused about the timeline for approval. Specifically, I'm wondering which application typically gets approved first between the I-130 Petition for Alien Relative and the I-485 Application to Register Permanent Residence or Adjust Status? Is there a general rule of thumb, or does it vary from case to case? Thank you for your help in clarifying this for me.
