How to post simultaneously on multiple social media accounts via Hootsuite & Buffer

This is how I post simultaneously on all social media accounts.

• Hootsuite hasn't had the ability to post on Linkedin yet. 
• Hootsuite and Buffer are free if you only connect 3 or less social media accounts. You will have to pay if you connect 4 social media accounts
• (I'm using my own personal brands ad demo. )
