Answer:
The system that models the situation is:

The solution is:
(9, 6)
Step-by-step explanation:
We must write the equations as indicated in the problem.
The sum of twice a number and another number is 24
<em>a number:</em> x
<em>other number:</em> y
Then

The difference of twice the first number and the other number is 12
<em>first number: </em> x
<em>other number:</em> y
Then:

The system that models the situation is:

To solve the system we add both equations to find the value of x
