The Main Challenge

This a number puzzle similar to my Mathelona series of challenges, but much more difficult.

Your task is to fill all 24 gaps below with the numbers 1-24. Each number should appear once each and ALL eight lines/equations must work out arithmetically.

◯   +   ◯   =   ◯
◯   +   ◯   =   ◯
◯   +   ◯   =   ◯
◯   +   ◯   =   ◯
◯   +   ◯   =   ◯
◯   +   ◯   =   ◯
◯   +   ◯   =   ◯
◯   +   ◯   =   ◯
