Answer:
The equations that represent correctly the problem are A. 108 - 2x = x and D. x + 2x = 108
Step-by-step explanation:
Oranges sold on Thursday = x
Oranges sold on Friday = 2x
Oranges sold on Thursday and Friday = 108
Formula for calculating the value of x :
x + 2x = 108
The correct answer to this question could be alternative D. x + 2x = 108, but if we take a closer look, we'll find that there are other valid options.
A. 108 - 2x = x
- 2x - x = - 108 (changing the positions and putting the variables on one side and the whole number on the other)
x + 2x = 108 (multiplying by - 1 at both sides and it's also correct)
B. 2x - x = 108 (This is incorrect because the sales of Thursday plus the sales of Friday equal to 108, not minus)
C. x + 108 = 2x
x - 2x = - 108 (This is also incorrect because the sales of Thursday plus the sales of Friday equal to 108, not minus)
Now, let's find the solution
x + 2x = 108
3x = 108
X = 36 (Oranges sold on Thursday)
2x = 72 (Oranges sold on Friday)
After doing all this explanations, we found that equations A and D represent the problem.
