The image contains a mathematical problem. Let's analyze and solve it step-by-step.

Given Equation:

$3 \log_5 (3x - 2) = 9$

Step 1: Simplify the equation

First, we can divide both sides of the equation by 3:

$\log_5 (3x - 2) = 3$

Step 2: Exponentiate both sides

To remove the logarithm, we exponentiate both sides of the equation with base 5:

$3x - 2 = 5^3$

Since $5^3 = 125$:

$3x - 2 = 125$

Step 3: Solve for $x$

Add 2 to both sides:

$3x = 127$

Then, divide by 3:

$x = \frac{127}{3}$

So, the solution to the equation is:

$x = \frac{127}{3} \approx 42.33$
