Answer:
The system cannot be solved by a unique cost for each soldier, because has infinite solutions
Step-by-step explanation:
Let
x-------> the cost of a legionary per day
y-------> the cost of an archer per day
we know that
------> equation A

equation A and equation B is the same equation
therefore
This is a consistent dependent system
The system has infinite solutions
