2x-1 + 2x+1 = 320
2x-1(1 + 22) = 320
2x-1 = 320
2x-1 = 320 / 5 = 64
2x-1 = 26
x - 1 = 6
x = 7

Given:
2x - 1 2x + 1 = 320

To find:
The value of x

Solution:
To solve this equation, we need to isolate the variable x.

Step 1:
Expand the equation by distributing the terms on the left side of the equation.

2x - 2x + 1 + 1 = 320

Simplifying the equation gives:

2 = 320

Step 2:
This equation is not possible as it leads to a contradiction. The left side of the equation is a constant value of 2, while the right side is a constant value of 320. Since the equation is invalid, it means that there is no solution for x in this equation.

Therefore, there is no value of x that satisfies the equation 2x - 1 2x + 1 = 320.

Conclusion:
The correct answer is option 'D' as there is no solution for x in the given equation.
