To solve this equation, we will follow the order of operations (PEMDAS/BODMAS).

First, we need to simplify the expression inside the parentheses:
17x - 25

Next, we divide the simplified expression by 8:
(17x - 25) / 8

Now, we subtract 65 from the result of the division:
(17x - 25) / 8 - 65

Finally, we check if the result is equal to 9 squared (81):
(17x - 25) / 8 - 65 = 9^2

Let's solve the equation step by step:

(17x - 25) / 8 - 65 = 9^2

First, let's simplify the left side of the equation:

(17x - 25) / 8 - 65 = 81

Next, let's multiply both sides of the equation by 8 to eliminate the fraction:

8 * [(17x - 25) / 8 - 65] = 8 * 81

This simplifies to:

17x - 25 - 520 = 648

Combine like terms:

17x - 545 = 648

Now, let's isolate the variable by adding 545 to both sides of the equation:

17x - 545 + 545 = 648 + 545

This simplifies to:

17x = 1193

Finally, divide both sides of the equation by 17 to solve for x:

(17x) / 17 = 1193 / 17

This simplifies to:

x = 70.176

Therefore, the solution to the equation is x = 70.176.
