To solve the equation $3x - 4 = 6$ using the change of base formula for logarithms, follow these steps:

1. Isolate the term with $x$:

   $3x - 4 = 6$

   Add 4 to both sides:

   $3x = 10$

2. Solve for $x$:

   $x = \frac{10}{3}$

   At this point, you can simplify:

   $x \approx 3.333$

Since the problem also mentions the change of base formula, let's apply it to understand its usage, even though it's not directly needed to solve this linear equation. The change of base formula for logarithms is:

$\log_b(y) = \frac{\log(y)}{\log(b)}$

However, since we are not dealing with logarithms in the equation $3x - 4 = 6$, and we have already solved for $x$ directly, there's no need to apply the change of base formula here.

The solution for $x$, rounded to the nearest thousandth, is:

$x \approx 3.333$
