Hello there!
The question asks us to solve using the substitution method. The equations given are:
We are given a value for y, which is x-8. Substituting into the first equation of the system of equation gives us:
Use the distributive property to help simplify and solve for x
Combine like terms
Add 24 to both sides
Finally, divide both sides by 5
Now, let's use in the equation to find the value of y
Now, we have the values x=5 and y=-3. Putting these values into an ordered pair gives us the answer (5,-3), which is the last answer choice.
Let me know if you need any clarifications, thanks!

Step-by-step explanation:
hope you can understand
Since the girl scout sold 5 more boxes on the second week, we have (x + 5) number of boxes sold for the second week. Now, for the third week, since it's double that of the second week, we have 2(x + 5). Thus, we have the following:
first week: x
second week: x + 5
third week: 2(x + 5)
Given that the total number of boxes sold for the three weeks is 431. We have
x + (x + 5) + 2(x + 5) = 431
x + x + 5 + 2x + 10 = 431
4x + 15 = 431
4x = 431 - 15
4x = 416
x = 104
We have now the value of x. Using this, we can find the values for the second and third week.
x + 5 = `104 + 5 = 109
2(x + 5) = 2(109) = 218
Answer:
first week: 104
second week: 109
third week: 218
We know, Circumference = 2π * x/2 = <span>π x
In short, Your Answer would be: Option B
Hope this helps!</span>
