    D is the Answer on Edgen.

    Step-by-step explanation:

    108 - 2x = x

    2x - x = 108

    x + 108 = 2x

    x + 2x = 108

    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.
