If you Add 2 to four times the length of the Amazon river, the result is 25,750. How do you find the length of the river?

let the length of the river be l

so four times the length = 4l and add 2 to this = 4l + 2

Now this result is equal to 25 750

hence 4l + 2 = 25 750

subtract 2 from both sides : 4l + 2 - 2 = 25 750 - 2

and 4l = 25 748

gives l = 6437

To find the length of the Amazon river, you would first subtract 2 from 25,750, and then divide the result by 4. This is because the problem states that the result of adding 2 to four times the length of the river is 25,750. Mathematically, it can be represented as:

(4x + 2 = 25750)

Where (x) represents the length of the river.

To solve for (x), first subtract 2 from both sides to isolate the term (4x), then divide both sides by 4:

(4x = 25750 - 2)

(4x = 25748)

(x = \frac{25748}{4})

(x = 6437)

So, the length of the Amazon river is 6,437 units (the units are not specified in the question).
