Lads I'm fucking retarded. I'm trying to understand this Diophantus riddle for myself. I'm obviously missing some elementary understanding of how the algebra breaks down for the final solution. I can understand up to:
x = 75x/84 + 9
but not sure how it breaks down from there.
Another website had the next step written like
Hence 9x/84 = 9 or x/84 = 1. So x = 84
How do they arrive at this?
