[Line School/Physics] Finding Weights supported by each Pulley Block.

[u/Titanically247]

Instructor drew this on the board earlier, and told us we have until Thursday to figure it out. He stated that we needed to find the missing weights, and that there was also something else crucial missing that we had to figure out. If someone could help me understand how to solve. Or tell me what I need to measure to have enough information to solve it, it would be a huge help.
