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:
Now we will solve for x from our 2nd equation,
Now we will substitute this value in our 1st equation.
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.

Answer:
7 1/24
Step-by-step explanation:
First, you have to get the fractions to have the same denominator. So, you take 2/3 and 3/8 and find the smallest number by multiplying for the denominator. That number is 24 because 3 times 8 is 24 and 8 times 3 is 24.
Then, you multiply both the denominator and the numerator by the number that you got for the fractions. 2 * 8 = 16 3 * 8 = 24. 3 * 3 = 9 8 * 3 = 24. So, that gives you 16/24 and 9/24. Now since they have the same denominator you can add them.
This gives you 25/24 which equals 1 1/24.
Next, you can add the whole numbers. That is 6.
Lastly, take your fraction answer and your whole number answer and you get 7 1/24.
I hope this helps! =)
6x(-3)= (-5x) + 7
-18x = -5x + 7
-18x + 5x = 7
-13x = 7
x = 7/-13
x= -7/13
