Assumption:

<em>Something is missing in question. If we see deeply it is apparent that there is some issue with option b i.e. </em><em>B) 8 − 4x 10 = 4 + 2x </em><em>we assume that the questioner want to type </em><em>B) 8-4x^10 = 4 + 2x.</em>

Answer:

The correct answer is <em> </em><em>B) 8-4x^10 = 4 + 2x.</em>

Step-by-step explanation:

All equations given is the question can be solve easily to determine the value of x. However if we solve equation mentioned in option b we cannot  get single answer easily.

For example value of x in eq given in option A

15x + 123 = 5x+4

1oX = -119

 X = -119/10
