The equation from the image is:

[ \left[\frac{\log_x a}{\log(b-7)} \cdot \frac{\log(3a+1)}{2}\right] = \left[\frac{\log b}{\log a} \cdot 1\right] ]

We are asked to find the value of $x$ that satisfies this equation. Let's break this down step-by-step:

Step 1: Simplify both sides

We have two logarithmic terms and constants involved. Start by simplifying the left-hand side and the right-hand side separately.

Left-hand side:

$\frac{\log_x a}{\log(b-7)} \cdot \frac{\log(3a+1)}{2}$ Using the change of base formula $\log_x a = \frac{\log a}{\log x}$, we rewrite this as: $\frac{\frac{\log a}{\log x}}{\log(b-7)} \cdot \frac{\log(3a+1)}{2} = \frac{\log a}{\log x \cdot \log(b-7)} \cdot \frac{\log(3a+1)}{2}$

Right-hand side:

The right-hand side is simpler: $\frac{\log b}{\log a} \cdot 1 = \frac{\log b}{\log a}$

Step 2: Set up the equality

Now that both sides are simplified, equate them:

$\frac{\log a}{\log x \cdot \log(b-7)} \cdot \frac{\log(3a+1)}{2} = \frac{\log b}{\log a}$

This equation needs to be solved for $x$.

Step 3: Multiply and isolate $x$

Multiplying both sides of the equation by the denominators and simplifying further will lead to isolating $x$, which can then be solved using logarithmic properties.
