The denarius was a unit of currency in ancient Rome. Suppose it costs the Roman government 10 denarius per day to support 3 legi

Romashka [77]

Answer:

We can not solve for a unique cost for each soldier.

Step-by-step explanation:

Let x be the daily cost for legionaries and y be the daily cost for archers.

Upon using our given information we will get a system of linear equations as:

$3x+3y=10...(1)$

$x+y=3...(2)$

Now we will solve for x from our 2nd equation,

$x = 3-y$

Now we will substitute this value in our 1st equation.

$3(3-y)+3y=10$

$9-3y+3y=10$

We can see that -3y cancels out with 3y and 9 is not equal to 10. So this is an unsolvable system. Therefore, we can not find a unique cost for each soldier.

x = 62*2

<h2>x = 124</h2>

3.

x = 108/2

<h2>x = 54</h2>

4.

x = 160/2

<h2>x = 80</h2>

5.

12x = 60*2

12x = 120

x = 120/12

<h2>x = 10</h2>

6.

5x = 50/2

5x = 25
