Marta's fruit stand sold many oranges on Thursday and twice as many on Friday. All together, on both days, she sold 108. Which equation represents the problem? 108 - 2x = x 2x - x = 108 x + 108 = 2x x + 2x = 108

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.
