To solve the inequality
\[
\frac{3(x - 6)}{2} \geq \frac{2x}{7} - 12,
\]
first, we clear the fractions by multiplying both sides by 14 (the least common multiple of 2 and 7):
\[
14 \cdot \frac{3(x - 6)}{2} \geq 14 \cdot \left(\frac{2x}{7} - 12\right).
\]
This simplifies to:
\[
7 \cdot 3(x - 6) \geq 4x - 168.
\]
Now simplify the left side:
\[
21(x - 6) \geq 4x - 168.
\]
Distributing 21 gives us:
\[
21x - 126 \geq 4x - 168.
\]
Next, isolate \(x\) by subtracting \(4x\) from both sides:
\[
21x - 4x - 126 \geq -168.
\]
This simplifies to:
\[
17x - 126 \geq -168.
\]
Now add \(126\) to both sides:
\[
17x \geq -168 + 126.
\]
Calculating the right side yields:
\[
17x \geq -42.
\]
Finally, divide both sides by 17:
\[
x \geq -\frac{42}{17}.
\]
Thus, the solution to the inequality is
\[
x \geq -\frac{42}{17}.
\]
