The denarius was a unit of currency in ancient Rome. Suppose it costs the Roman government 10 denarii per day to support 4 legionaries and 4 archers. It only costs 5 denarii per day to support 2 legionaries and 2 archers.

 

Can we solve for a unique cost for each soldier?

No, you can't    

 

4 L + 4 A = 10     is basically the same equation as

2 L  + 2 A  = 5     (just divided by 2)
