How can I remove my LinkedIn account forever?

I created a LinkedIn account because I am strong at video editing and thought it would help me obtain business, but it was completely worthless. In order to handle some of my posts on my own, I decided to get a part-time job in addition to my studies. I wanted to work for myself because I frequently had to pay for the reliable assignment help online I purchase for writing aid. However, other than the daily, unlimited alerts from this site, I received nothing from it. Can someone please tell me how to remove this account forever?
