Farmer joe had 3 animals, he wanted to weight Lucy, Nancy and Sue. He only had a scale that started with 100kg. Now, as heavy as those animals were, none of them exceeded 100kg.so he weighted them in pairs. Lucy and Nancy weight 132 kg together and Sue and Lucy weight 137 kg together. How much did each weight individually?

You will need one more weighing. I suggest Nancy and Sue.

You have three unknowns, it will take three equations to solve for the unknowns.

sorry don't know and im really good ar math
