Answer:
The solution of the system of linear equations is and .
Step-by-step explanation:
Let and expressions of the system of linear equations. Since the number of variables and equations are the same, there is only one solution and we can solve it by algebraic means:
(1)
(2)
From (1):
By applying (1) in (2):
By (1):
The solution of the system of linear equations is and .

Step-by-step explanation:
Answer:
16.095.
Step-by-step explanation:
We can either find 37% of both the numbers and add the results, or we can add the numbers and then find the 37% of the sum.
1. Let us find 37% of both numbers separately.
First of all we will convert our mixed fraction into improper fraction.
37% of will be,
Now let us find 37% of 15.9.
Now let us add 37% of both numbers.
Therefore, 37% of our given numbers will be 16.095.
2. Now we will add both numbers and then find 37% of their sum.
Now let us find 37% of 43.5.
Therefore, 37% of 43.5 is 16.095. We have seen that using either way we got the same answer.
