Amanda [17]

Answer:

x = 8

Step-by-step explanation:

By first drawing a photo, pasted below, you can plot your points. Then use the formula:

a/c = b/d to plan out your equation

3x - 8/x = 16/x

Cross multiply so you then have:

16x = 3x^2 - 8x

24x = 3x^2

8 = x

To check:

3(8) - 8 = 16

24 - 8 = 16

16 = 16

The answer is A.

Step-by-step explanation:

Excluded values are values that will make the denominator of a fraction equal to 0. You can't divide by 0, so it's very important to find these excluded values when you're solving a rational expression.
